The structure of the catalyst was established by infrared, energy dispersive x-ray (EDX), and scanning electron microscopy analyses. The reactions proceed smoothly to furnish the respective products in excellent yields and short reaction times. The facile reaction conditions, easy isolation of the products, versatility, and easy magnetic separation and reusability of the catalyst with no significant loss of activity are the main merits of the present method.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4KPHJlc291cmNlIHhtbG5zOnhzaT0iaHR0cDovL3d3dy53My5vcmcvMjAwMS9YTUxTY2hlbWEtaW5zdGFuY2UiIHhtbG5zPSJodHRwOi8vZGF0YWNpdGUub3JnL3NjaGVtYS9rZXJuZWwtNCIgeHNpOnNjaGVtYUxvY2F0aW9uPSJodHRwOi8vZGF0YWNpdGUub3JnL3NjaGVtYS9rZXJuZWwtNCBodHRwOi8vc2NoZW1hLmRhdGFjaXRlLm9yZy9tZXRhL2tlcm5lbC00L21ldGFkYXRhLnhzZCI+CiAgPGlkZW50aWZpZXIgaWRlbnRpZmllclR5cGU9IkRPSSI+MTAuNjA4NC9NOS5GSUdTSEFSRS5DLjI4Njc0MzcuVjI8L2lkZW50aWZpZXI+CiAgPGNyZWF0b3JzPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZT5EYXZvb2QgQXphcmlmYXI8L2NyZWF0b3JOYW1lPgogICAgPC9jcmVhdG9yPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZSBuYW1lVHlwZT0iUGVyc29uYWwiPkFiYmFzaSwgWW91bmVzPC9jcmVhdG9yTmFtZT4KICAgICAgPGdpdmVuTmFtZT5Zb3VuZXM8L2dpdmVuTmFtZT4KICAgICAgPGZhbWlseU5hbWU+QWJiYXNpPC9mYW1pbHlOYW1lPgogICAgPC9jcmVhdG9yPgogIDwvY3JlYXRvcnM+CiAgPHRpdGxlcz4KICAgIDx0aXRsZT5TdWxmb25pYyBhY2lk4oCTZnVuY3Rpb25hbGl6ZWQgbWFnbmV0aWMgRmUmbHQ7c3ViJmd0OzMteCZsdDsvc3ViJmd0O1RpJmx0O3N1YiZndDt4Jmx0Oy9zdWImZ3Q7TyZsdDtzdWImZ3Q7NCZsdDsvc3ViJmd0OyBuYW5vcGFydGljbGVzOiBOZXcgcmVjeWNsYWJsZSBoZXRlcm9nZW5lb3VzIGNhdGFseXN0IGZvciBvbmUtcG90IHN5bnRoZXNpcyBvZiB0ZXRyYWh5ZHJvYmVuem9bYl1weXJhbnMgYW5kIGRpaHlkcm9weXJhbm9bMiwzLWNdcHlyYXpvbGUgZGVyaXZhdGl2ZXM8L3RpdGxlPgogIDwvdGl0bGVzPgogIDxwdWJsaXNoZXI+Rmlnc2hhcmU8L3B1Ymxpc2hlcj4KICA8cHVibGljYXRpb25ZZWFyPjIwMTY8L3B1YmxpY2F0aW9uWWVhcj4KICA8cmVzb3VyY2VUeXBlIHJlc291cmNlVHlwZUdlbmVyYWw9IkNvbGxlY3Rpb24iPkNvbGxlY3Rpb248L3Jlc291cmNlVHlwZT4KICA8c3ViamVjdHM+CiAgICA8c3ViamVjdD5CaW9waHlzaWNzPC9zdWJqZWN0PgogICAgPHN1YmplY3Q+QmlvY2hlbWlzdHJ5PC9zdWJqZWN0PgogICAgPHN1YmplY3Qgc3ViamVjdFNjaGVtZT0iRk9SIj4yOTk5OSBQaHlzaWNhbCBTY2llbmNlcyBub3QgZWxzZXdoZXJlIGNsYXNzaWZpZWQ8L3N1YmplY3Q+CiAgICA8c3ViamVjdCBzdWJqZWN0U2NoZW1lPSJGaWVsZHMgb2YgU2NpZW5jZSBhbmQgVGVjaG5vbG9neSAoRk9TKSIgc2NoZW1lVVJJPSJodHRwOi8vd3d3Lm9lY2Qub3JnL3NjaWVuY2UvaW5uby8zODIzNTE0Ny5wZGYiPkZPUzogUGh5c2ljYWwgc2NpZW5jZXM8L3N1YmplY3Q+CiAgICA8c3ViamVjdCBzdWJqZWN0U2NoZW1lPSJGaWVsZHMgb2YgU2NpZW5jZSBhbmQgVGVjaG5vbG9neSAoRk9TKSI+Rk9TOiBQaHlzaWNhbCBzY2llbmNlczwvc3ViamVjdD4KICAgIDxzdWJqZWN0Pk1lZGljaW5lPC9zdWJqZWN0PgogICAgPHN1YmplY3Q+Q2VsbCBCaW9sb2d5PC9zdWJqZWN0PgogICAgPHN1YmplY3Q+UGh5c2lvbG9neTwvc3ViamVjdD4KICAgIDxzdWJqZWN0IHN1YmplY3RTY2hlbWU9IkZpZWxkcyBvZiBTY2llbmNlIGFuZCBUZWNobm9sb2d5IChGT1MpIiBzY2hlbWVVUkk9Imh0dHA6Ly93d3cub2VjZC5vcmcvc2NpZW5jZS9pbm5vLzM4MjM1MTQ3LnBkZiI+Rk9TOiBCaW9sb2dpY2FsIHNjaWVuY2VzPC9zdWJqZWN0PgogICAgPHN1YmplY3Qgc3ViamVjdFNjaGVtZT0iRmllbGRzIG9mIFNjaWVuY2UgYW5kIFRlY2hub2xvZ3kgKEZPUykiPkZPUzogQmlvbG9naWNhbCBzY2llbmNlczwvc3ViamVjdD4KICAgIDxzdWJqZWN0PlBoYXJtYWNvbG9neTwvc3ViamVjdD4KICAgIDxzdWJqZWN0PkJpb3RlY2hub2xvZ3k8L3N1YmplY3Q+CiAgICA8c3ViamVjdCBzdWJqZWN0U2NoZW1lPSJGT1IiPjM5OTk5IENoZW1pY2FsIFNjaWVuY2VzIG5vdCBlbHNld2hlcmUgY2xhc3NpZmllZDwvc3ViamVjdD4KICAgIDxzdWJqZWN0IHN1YmplY3RTY2hlbWU9IkZpZWxkcyBvZiBTY2llbmNlIGFuZCBUZWNobm9sb2d5IChGT1MpIiBzY2hlbWVVUkk9Imh0dHA6Ly93d3cub2VjZC5vcmcvc2NpZW5jZS9pbm5vLzM4MjM1MTQ3LnBkZiI+Rk9TOiBDaGVtaWNhbCBzY2llbmNlczwvc3ViamVjdD4KICAgIDxzdWJqZWN0IHN1YmplY3RTY2hlbWU9IkZpZWxkcyBvZiBTY2llbmNlIGFuZCBUZWNobm9sb2d5IChGT1MpIj5GT1M6IENoZW1pY2FsIHNjaWVuY2VzPC9zdWJqZWN0PgogIDwvc3ViamVjdHM+CiAgPGRhdGVzPgogICAgPGRhdGUgZGF0ZVR5cGU9IkNyZWF0ZWQiPjIwMTYtMDUtMTM8L2RhdGU+CiAgICA8ZGF0ZSBkYXRlVHlwZT0iVXBkYXRlZCI+MjAxNi0wNi0wMTwvZGF0ZT4KICAgIDxkYXRlIGRhdGVUeXBlPSJJc3N1ZWQiPjIwMTY8L2RhdGU+CiAgPC9kYXRlcz4KICA8cmVsYXRlZElkZW50aWZpZXJzPgogICAgPHJlbGF0ZWRJZGVudGlmaWVyIHJlbGF0ZWRJZGVudGlmaWVyVHlwZT0iRE9JIiByZWxhdGlvblR5cGU9IklzU3VwcGxlbWVudFRvIj4xMC4xMDgwLzAwMzk3OTExLjIwMTYuMTE3MTM2MDwvcmVsYXRlZElkZW50aWZpZXI+CiAgICA8cmVsYXRlZElkZW50aWZpZXIgcmVsYXRlZElkZW50aWZpZXJUeXBlPSJET0kiIHJlbGF0aW9uVHlwZT0iSXNJZGVudGljYWxUbyI+MTAuNjA4NC9tOS5maWdzaGFyZS5jLjI4Njc0Mzc8L3JlbGF0ZWRJZGVudGlmaWVyPgogIDwvcmVsYXRlZElkZW50aWZpZXJzPgogIDxzaXplcy8+CiAgPGZvcm1hdHMvPgogIDx2ZXJzaW9uLz4KICA8cmlnaHRzTGlzdD4KICAgIDxyaWdodHMgcmlnaHRzVVJJPSJodHRwOi8vY3JlYXRpdmVjb21tb25zLm9yZy9saWNlbnNlcy9ieS8zLjAvdXMiPkNDLUJZPC9yaWdodHM+CiAgPC9yaWdodHNMaXN0PgogIDxkZXNjcmlwdGlvbnM+CiAgICA8ZGVzY3JpcHRpb24gZGVzY3JpcHRpb25UeXBlPSJBYnN0cmFjdCI+SW4gdGhpcyB3b3JrLCB0aXRhbm9tYWduZXRpdGUgbmFub3BhcnRpY2xlcyAoRmUmbHQ7c3ViJmd0OzMteCZsdDsvc3ViJmd0O1RpJmx0O3N1YiZndDt4Jmx0Oy9zdWImZ3Q7TyZsdDtzdWImZ3Q7NCZsdDsvc3ViJmd0OykgaGF2ZSBiZWVuIHVzZWQgYXMgYSBub3ZlbCBzdXBwcG9ydCBmb3IgdGhlIHN5bnRoZXNpcyBvZiBhIG1hZ25ldGljIGFjaWRpYyBjYXRhbHlzdC4gVGhlc2UgbmFub3BhcnRpY2xlcyB3ZXJlIGZ1bmN0aW9uYWxpemVkIHdpdGggc3VsZm9uaWMgYWNpZCBncm91cHMgdG8gcHJlcGFyZSB0aGUgRmUmbHQ7c3ViJmd0OzMteCZsdDsvc3ViJmd0O1RpJmx0O3N1YiZndDt4Jmx0Oy9zdWImZ3Q7TyZsdDtzdWImZ3Q7NCZsdDsvc3ViJmd0O0BTTyZsdDtzdWImZ3Q7MyZsdDsvc3ViJmd0O0ggbmFub3BhcnRpY2xlcy4gVGhlIHN5bnRoZXNpemVkIGFjaWRpYyBuYW5vcGFydGljbGVzIGhhdmUgYmVlbiBleHBsb3JlZCBhcyBuZXcgYW5kIGVmZmljaWVudCByZWN5Y2xhYmxlIGhldGVyb2dlbmVvdXMgY2F0YWx5c3QgZm9yIGEgb25lLXBvdCwgdGhyZWUtY29tcG9uZW50IHN5bnRoZXNpcyBvZiB0ZXRyYWh5ZHJvYmVuem9bYl1weXJhbnMga25vd24gYXMgNCZsdDtpJmd0O0gmbHQ7L2kmZ3Q7LWNocm9tZW5lcyBhbmQgMSw0LWRpaHlkcm9weXJhbm9bMiwzLWNdcHlyYXpvbGVzLiBUaGUgc3RydWN0dXJlIG9m
