✦ Synopsis

The synthesis of the title compounds where the heteroatoms are silicon, tin, lead and sulphur and mercury is demonstrated. Some of these derivatives readily form anions of structural and chemical interest.

We have shown that carbanions stabilised by an c1 boron atom can be readily synthesised and are of considerable synthetic utility.

The bulky dimesitylboron group encourages the formation of an o-carbanion from dimesitylalkylboranes by proton abstraction by a relatively hindered base, as compared with ate complex formation. It also stabilises the carbanion so formed. However the dimesitylboron group allows ate complex formation

Alkyldimesitylboranes, yield anions', by oxidation give 1,3-diols. ## These anions Mes2BCHR. that on reaction with oxiranes followed are thus the operational equivalent of RCHOH. The scope and limitations of the new process are delineated.
