Stable compounds of 2-coordinate phosphorus were synthesized, namely, (bis(trimethylsilyl)methyl)fluorenylidenephosphine and (bis(trimethylsilyl)methylene)fluorenylphosphine, which are isomers differing in the position of the hydrogen atom in the triad .C .../over bond P .../over bond C. 1,3-Prototropic alkylphosphaalkene rearrangement was effected. 1,3-Prototropic migration in the triad C .../over bond P .../over bond C is limited by the high energy barrier present and is distinguished by low prototropic mobility. Strong bases (diazabicycloundecane, (bis(trimethylsilyl)amino)lithium) catalyze alkylphosphaalkene rearrangement.
