Organosilicon and organotin derivatives of urea in transmetallation reactions

Reaction of N-trimethylsilyl-N'-phenylurea with bis(tributylstannyl) oxide in refluxing THF yields tributylstannyl isocyanate and aniline as the main products, while in the case of triphenylstannyl chloride N-triphenylstannyl-N'-phenylurea can be prepared. Its thermal decomposition yields...

Summary:Reaction of N-trimethylsilyl-N'-phenylurea with bis(tributylstannyl) oxide in refluxing THF yields tributylstannyl isocyanate and aniline as the main products, while in the case of triphenylstannyl chloride N-triphenylstannyl-N'-phenylurea can be prepared. Its thermal decomposition yields triphenylstannyl isocyanate and aniline. Reaction of N,N'-bis(trimethylstannyl)urea with (Bu3Sn)(2)O gives Bu3Sn-N=C=O, HMDS, and ammonia.
