Reactions of Diphenylphosphane Oxide with Organodiboranes(6) - Structure of a Zwitterionic Compound
(C6H5)2POB(C2H5)2 (3'a), prepared from diphenylphosphane oxide (C6H5)2P(O)H (1) and activated triethylborane (2a*), reacts with tetraalkyldiboranes(6) (R2BH)2 to form the BH3-addition compounds (C6H5)2P(BH3)OBR2 , 2BR , and 3B .The reaction of bis(9-borabicyclononane) (4c)2 with 1 leads to (C6H5)2POBC8H14 (3'c) or 3'c-4a and (C6H5)2PH (7) or (C6H5)2PH-HBC8H14 (7-4c).The crystalline zwitterionic (C6H5)2P(H)OB3 (X-ray analysis) is isolated from the reaction of 1 with (4a)2.
