摘要:
Treatment of the di-lt-chloride allyl-palladium complex [(eta (3)-C3H5)Pd(mu -Cl)(2)Pd(eta (3)-C3H5)] with Pb(SR)(2) in acetone affords dinuclear fluorothiolate bridged complexes of the type [(eta (3)-C3H5)Pd(mu -SR)(2)Pd(eta (3)-C3H5)] (R = C6F5, 1; C6HF4-4, 2: C6H4F-2, 3; C6H4F-3, 4 and C6H4F-4, 5). Complex 1 reacts with pares-substituted phosphines P(C6H4X-4)(3) to give the mononuclear perfluorobenzenethiolate complexes [Pd(SC6F5)(eta (3)-C3H5)(P(C6H4X-4)(3))] (X = F, 6; CF3, 7; OCH3, 8 and CH3, 9). The single crystal X-ray diffraction structure of [(eta (3)-C3H5)Pd(mu -SC6H4F-4)(2)Pd(eta (3)-C3H5)] (5) has been resolved. (C) 2001 Published by Elsevier Science Ltd.
