Preparation and Isomerization of 3,4-Bis(2,4,6-tri-t-butylphenylphosphinidene)cyclobutenes

(E,E)- and (E,Z)-3,4-Bis(2,4,6-tri-t-butylphenylphosphinidene)cyclobutenes were prepared by desilylation reaction of the corresponding 1,2-bis(trimethylsilyl)cyclobutenes or by thermal isomerization reaction of 1,6-bis(2,4,6-tri-t-butylphenyl)-1,6-diphosp

1λ3?2,6λ3?2-Diphospha-1,2,4,5-hexatetraen aus 1,6-Di-H-1,6-diphosphino-2,4-hexadiin

1,6-Di-H-1,6-diphosphino-2,4-hexadiyne 5 undergoes a base-catalyzed heteropropargylic rearrangement to give 1,6-diphosphahexatetraene 3a, which forms stereoselective 3,4-diphosphamethylencyclobutene 4a by valence isomerisation.
