N, N-dialkyl carbamates decompose in strongly acidic media to carbon dioxide, olefin, alkyl halide and alcohol, the rate of reaction of the secondary esters closely following the acidity function. This fact, together with the variation in rate of hydrolysis of carbamates of cyclic alcohols with the ring size, shows that, unlike the solvolyses of the corresponding chloroformates which lead to carboxonium
