showed at least some tendency to revert to the starting dichloro complexes by loss of the methylene moiety. Products of insertion into a Pd–Br bond are less readily formed than those of the corresponding chloride and the resulting bromomethyl derivatives are less stable than their chloromethyl analogues. Chloromethyl derivatives were also prepared from the dichloride by treatment with bis(chloromethyl)mercury

Air-stable dihalogenomethylchromium(III) ions are the main products of reduction of chloroform, bromoform, and iodoform with less than two equivalents of chromous perchlorate or fluoroborate. With four or more equivalents of chromous perchlorate the main products are the corresponding air-stable monohalogenomethylchromium(III) ions. Methylchromium(III) ion cannot be detected in the products. These
