摘要

The silane-induced cleavage of a series of Np-tolylcarbamates and N-phenethylcarbamates to isocyanates has been investigated as a function of chlorosilane, carbamate substituent, and reaction conditions. Reaction yields were determined from the isolated ureas, which were formed by trapping the corresponding isocyanates with isobutylamine. Under room- temperature conditions, multilevel selectivity in carbamate activation has been ...
