REACTIONS DE LA DICHLOROPHENYLPHOSPHINE AVEC LES IMINES: SYNTHESE DES DIHYDRO-1,2 λ3-AZAPHOSPHININES-1,2 ET DES OXO-2 AZAPHOSPHOLENES-1,2,4

The reaction of one equivalent of dichlorophenylphosphine with two equivalents of aliphatic imines gives a mixture of 1,2-dihydro 1,2 λ3-azaphosphinines 2 and 2-oxo 1,2,4-azaphospholenes 3.Compounds 2 are the major product when the imines are prepared from amines with bulky group.The yield of azaphospholenes 3 is enhanced when the dichlorophenylphosphine is used in excess.Oxidation of azaphosphinines 2 with hydrogen peroxide gives 2-oxo 1,2-azaphosphinines 4.

SYNTHESIS OF THE 1,2-DIHYDRO 1,2-λ3-AZAPHOSPHORINES

1,2-Dihydro 1,2-λ3-azaphosphorines were prepared by reaction of dichlorophenylphosphine with two equivalents of imines. 2-Oxo 1,2-azaphospholenes were also obtained in some cases.

FIRST SYNTHESIS OF 1,2-DIHYDRO 1,2-λ3-AZAPHOSPHORINES

1,2-dihydro 1,2-λ3-azaphosphorines were prepared by reaction of dichlorophenylphosphine with two equivalents of imines derived from propanal.In some cases, 2-oxo 1,2-azaphospholenes were also obtained.
