An investigation of the thermal decomposition of the methohydroxides and methodeuterio-oxides of some 5-N,N-dimethylaminopent-1-enes
Abstract
The base-catalysed thermal decomposition of a number of quaternary bases of the type (R1)2CCHC(R2)2C(R3)2CH2NMe3X–(R1= H, Me; R2= H, 2H; R3= H, 2H, Me; X = OH,O2H) has been investigated. It is shown that the reaction is initiated by attack of base (ŌH, Ō2H, ylide) on an allylic proton or [2H]. A mechanism for the reaction is suggested.
