Reaction of bis(triphenyltin) oxide with thiourea and some 1,3-disubstituted thioureas

Add time:08/14/2019    Source:sciencedirect.com

Bis(triphenyltin) oxide was found to react with thiourea in refluxing acetonitrile to give bis(triphenyltin) sulfide, bis(triphenylstannyl)carbodiimide, and dicyandiamide. Bis(triphenylstannyl)carbodiimide was prepared by the reaction of bis(triphenyltin) oxide with cyanamide in refluxing acetonitrile or benzene. Bis(triphenyltin) oxide was found to react with 1,3-disubstituted thioureas in refluxing acetonitrile or toluene to give bis(triphenyltin) sulfide and, with the exception of di-tert-butylthiourea, the corresponding 1,3-disubstituted urea.
