It is shown by dynamic 1H-NMR spectroscopy that 1 exhibits thermal E/Z-isomerization of the double bond at ambient temperature. Reactions of 1 involve electrophilic attack of the π-system with hard (H+) and soft (Ag+) Lewis-acids, and an unusual cleavage of a PC-single bond on reaction with metal complexes (MeCN)3M(CO)3, (M = Mo, W).deinfo:eu-repo/semantics/openAccessMethylenphosphane , Phosphoalkene540Einfachbindungarticle2012-09-03
