## Abstract The influence of a ฮฒโ€methyl group on the reactivity of two stereoisomeric vinyl bromides has been studied. In 80% ethanol __cis__โ€(**8**) and __trans__โ€ฮฑโ€bromoanethole (**9**) undergo first order reactions leading to __p__โ€methoxypropiophenone (**15**), 1โ€ethoxyโ€1โ€(__p__โ€anisyl)โ€propene
