REDUCTION OF DIPHOSPHENE: FORMATION OF d1- AND meso-DIPHOSPHANES

Bis(2,4,6-tri-tert-butylphenyl)diphosphene was reduced with aluminium hydrides to give d1- and meso-bis(2,4,6-tri-tert-butylphenyl)diphosphanes as stable compounds.

Evidence for Iron-Catalyzed α-Phosphinidene Elimination with Phenylphosphine

The ubiquitous half-sandwich iron complex [CpFe(CO)2Me] (Cp=η5-C5H5) appears to be a catalyst for α-phosphinidene elimination from primary phosphines. Dehydrocoupling reactions provided initial insight into this unusual reaction mechanism, and trapping reactions with organic substrates gave products consistent with an α elimination mechanism, including a rare example of a three-component reaction. The substrate scope of this reaction is consistent with generation of a triplet phosphinidene. In all, this study presents catalytic phosphinidene transfer to unsaturated organic substrates.

Towards the Synthesis of o-Diphosphaquinones: Benzodiphosphadihydropentalene - Naphthodihydrodiphosphete

o-Quinodimethanes 1 are important intermediates in organic synthesis that may be generated by thermal valence isomerization of benzocyclobutenes or octa-1,2,4,6,7-pentaenes.The preparation of a stable o-quinodimethane has not been reported so far.Whereas o-quinodiimines 2 containing strongly electron-withdrawing groups at the nitrogen atoms are isolable, o-diphosphaquinones 3 have not been detected. - Keywords: Propargyl rearrangement; DBU; Electrocyclization; Diphosphaquinone; Dihydrodiphosphete
