Trialkyl phosphites P(OR)3 react with tetraalkyldiboranes(6) (R'2-BH)2 in a temperature-dependent manner between 20 and 130 deg C to form the trialkyl phosphite-boranes (RO)3P-BHR'2, (RO)3P-BH2R', and (RO)3P-BH3, which have various stabilities toward alcohols.With bis(9-borabicyclononane) (1c)2 the easily protolyzed addition compounds are obtained . - Diorgano phosphites (RO)2P(O)H , triorgano phosphates (RO)3PO , and the monosaccharide-diphenyl phosphates 4f, 4g, and 4h are reduced by (1a)2 or (1c)2 to give H2, PH3, and insoluble yellow phosphorus compounds, respectively.Phosphoric acid (4e), their derivatives OP(OBR2)3 , and phenylphosphonic acid C6H5P(O)(OH)2 (6) are not deoxygenated at 130 deg C by (1a)2 to (1c)2. - Diorganophosphoiic acids R2P(O)OH and phenylphosphinic acid C6H5(H)P(O)OH (5c) are reduced by (1a)2-(1c)2.Reaction of 5a with (1a)2 leads to the compounds B(C2H5)2 (8a-BH3), 2BC2H5 , and 3B . 5a reacts with (1c)2 under simultaneous formation of (C6H5)2PH (7) or (C6H5)PH-HBC8H14 (7-1c) and (C6H5)2POBC8H14 (8c) or (C6H5)2P(OBC8H14)-HBC8H14 (8c-1c). - 6 reacts with tetraethyldiboroxane (11a) to form a mixture of the oligomeric compounds - n - (6'a)n.
