Fluoroalicyclic Derivatives of Metals and Metalloids

Abstract

This article will be concerned with the preparation and properties of alicyclic fluorocarbon (fluoroalicy clic) derivatives of metals and metalloids. The discussion will be restricted to compounds containing the fluoroalicyclic ring sigma-bonded to elements other than carbon, nitrogen, oxygen, and the halogens, although inevitably, the chemistry of some compounds from this latter group will need to be described. Complexes, in which the metal or metalloid is a part of a ring, such as are excluded as are n complexes of fluoroalicyclic olcfins that some authors regard as metallocyclopropanes. The general class of sigma-bonded fluorocarbon derivatives of metals and metalloids has been known for some time. Most of the early work was concerned with the chemistry of trifluoroiodomethane and the preparation of trifluoromethyl derivatives, such as (CF), Hg. Since then fluoroaliphatic derivatives of many transition metals have been prepared, and some interest has been shown in studying vinylic and acetylenic derivatives.
