Conclusions
-
1.
A study was made of the reactions of organic isocyanates with various organosilazanes containing hydrogen or a hydrocarbon group on the nitrogen atom.
-
2.
The reactions of organosilazanes with organic isocyanates at 30–35° and atmospheric pressure occur by the transfer of the silyl group (CH3)3Si to the nitrogen of the isocyanato group, as a result of which urea derivatives are formed.
-
3.
In the reaction of l-phenyl-l,3-bistrimethylsilylurea with phenyl isocyanate isocyanatotrimethylsilane and l,3-diphenyl-1-(trimethylsilyl)urea were isolated.
-
4.
Six new compounds were isolated and characterized.
