  摘要：

  Thermal decompositions of the N-oxides derived from N,N-dimethyl-1-methylcycloalk,lamines II having eight-, nine- and ten-membered rings yield olefin mixtures containing 98.6, 94.0 and 97.5%, 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 methylenecycloalkanes and 1-methylcycloalkenes (predominantly cis), violation of the Hofmann rule being at a maximum in the decomposition of the nine-membered quaternary hydroxide. Importance of relative product stabilities and the operation of non-bonded interactions are discussed as possible explanations for the observed directions of elimination. Thermal decompositions of the N-oxides and quaternary hydroxides of dimethylcycloalkvimethylamines IV containing eight-, nine- and ten-membered rings proceed as expected with formation of the corresponding methylenecycloalkanes.

  The cleavage of the title compounds () in methanolic potassium hydroxide gives mixtures of olefins and α-methoxyolefins in good yields. The ratio of the products is dependent on the size of the carbocydic ring. The mechanism proposed involves cleavage of to the corresponding allylic chloride (). Solvolysis of the chloride gives the α-methoxyolefin. Alternatively, oxidative addition of to Pd(0) generates
