Abstract

Thermal decompositions of the K-oxides derived from K, K-dimethyl-1- methylcycloalkylamines I1 having eight-, nin2-and ten-membered rings yield olefin mixtures containing 98.6, 94.0 and Y7. 5yO, respectively, of 1-methylcycloalkenes. Considerable amounts of the trans isomers are formed from the nine-and ten-membered N-oxides. Pyrolyses of the corresponding quaternary hydroxides produce mixtures of ...
