Abstract

Cis‐4‐Phenyl‐buten‐(3)‐on‐(2) und cis‐3‐Phenyl‐propen‐(2)‐al‐(1) wurden mit den schon bekannten entsprechenden trans‐Verbindungen verglichen. Die beiden cis‐Verbindungen sieden 12 bzw. 15° tiefer als die trans‐Verbindungen. Sie sind ferner sehr säureempfindlich. Das cis‐4‐Phenyl‐buten‐(3)‐on‐(2) ist gegen Alkali beständig. Die beiden cis‐ und trans‐Produkte wurden durch die Semicarbazone, Phenyl‐semicarbazone und IR.‐Spektren charakterisiert. Das cis‐4‐Phenyl‐buten‐(3)‐on‐(2) gab ein Phenylsemicarbazid‐Phenylsemicarbazon, das 3‐Phenyl‐propen‐(2)‐al‐(1) dagegen ein einfaches Phenylsemicarbazon.

For compounds in which the geminal group is replaced by a single methyl or ethyl group, formation of a 6-ring could not be excluded theoretically. Practically, in this case also no ring closure occured. It is concluded that ring closure to carbocyclic compounds fails when the geminal dimethyl group
