✦ Synopsis

The reactlon of the title compound Cy with methyl lo&de gives the yllde J_ and the phosphonlum salt 4. The intermediate formation of the phosphonlaalkene p 1s postulated Tertiary phosphlnes are, as a rule, qood nucleophlles'.

In contrast, derivatives of two-ccordinate trivalent phosphorus have a rather low baslclty and nucleophillcity. Thus, attempts to pro-
