Urease carries out the hydrolysis of carbamide but not of butyl carbamide the C4H9 group cannot find room where H can. 

Carbutamide, Butyl carbamide, Clybutamide [339-43-5], antidiabetic, 35. Phosgene is used to prepare the symmetrical N,N -benzenesulfonyl urea 33 [32-34]. 

X-ray crystallography is by now one of the most important methods for the determination of carbanion structures. From the very large number of recently characterized carbanions only a few can be mentioned here. They include preparatively important species such as the first lithiated carbamide [29], the lithium and tetra- -butyl ammonium salts of a a-sulfonyl substituted carbanion [30], and a protoype of the synthetically very useful Lochmann bases. [31] On the other hand structural work - both by X-ray crystallography and by various modem NMR spectros-...
