Abstract
Bis [bis (dimethylamino) boryl] dibromobenzyl - amine - palladium - bromide C6H5C (Br2) - N {B [N (CH3)2]2}2PdBr and the corresponding iodo complex react with phosphines like (C6H5)3P or (C6H5)2P-CH2-CH2-P(C6H5)2 in benzene solution under substitution of the diborylamine ligand. Substitution products are {[(CeH5) 3P]2PdBr}2, [(CeH5) 2P (CH2)2 P (C6H5) 2PdBr] 2 and [(C6H5)2P(CH2)2P(CeH5)2PdJ]2, diamagnetic crystalline compounds. On the contrary the dimeric C6H5C(J2) - N{B[N(CH3)2]2}2PdJ and P(CeH5)3 form a complex with the formula C6H5C(J2)-N{B[N(CH3)2]2}2PdJ[P(C6H5)3]2. Here the diborylamine seems to be co ordinated only by one BN2-group. The other BN2-group of the starting material is substituted by the first, the co ordinated iodine atom of the Pd-J-Pd-bridge by the second phosphine molecule. A solution of this phosphine complex in CH2Cl2 leads to yellow crystals of [(CeH5) 3PPdJ] n.Keywords
