(a, parent compound; b, 4,5-dimethyl derivative) and of their pentacarbonyltungsten complexes 7 is described starting from dichloro(diiodomethyl)phosphine (2), which was prepared via alkylation of phosphorus trichloride with (diiodomethyl)magnesium chloride (1). The halogen−metal exchange reactions of 5a/b and 7a/b are reported: the lithiation reactions of 5a/b with n-BuLi were not successful. In contrast
