Abstract Dinuclear Pd(II) and Pt(II)-halides bearing bridged π-conjugated groups, trans,trans-[(PR3)2(X)M–Ar–M(X)>(PR3)2] (M = Pd, Pt; X = Cl, Br; ArH2 = terpyridine, fluorenone, benzyl, benzthiadiazole) were prepared from the double oxidative addition of dihalo-π-conjugated moieties (6,6’-dibromo-2,2’:6’,2”-terpyridine; 2,7-dibromo-9-fluorenene; 4,4’-dibromobenzil, 4,7-bis(2-bromo-5-thienyl)-2,1,3-benzthiadiazole) to the Pd(styrene)(PR3)2. In addition, when the dihalosilole derivatives (2,5-dibromo-1,1-dimethyl(or diphenyl)-3,4-diphenylsilole) reacted with Pd(styrene)(PR3)2, mono or dinuclear Pd(II) complexes bearing the dimethyl(or diphenyl)-3,4-diphenylsilole group were obtained. The obtained comopunds were characterized by spectroscopic and elemeantal analyses. π-Conjugated extension reactions of dinuclear Pd(II) halides bridged by bithiophene group with HC≡C-R {R = SiPh3, C(O)OMe }in the presence of CuI and HNEt2 caused the selecltive formation of bis(acetylide) Pd(II) complexes, Pd(C≡C-R)2(PR3)2 and bithiophene. Experimetal details will be discussed.
