摘要：

Alkynylpalladium halides trans-PdX (C = CR)(PMe3)2 [1, 2, 4, X = Cl, R = SiMe3, (CH2)2CH3, (CH2)5CH3; 3, X = Br, R = (CH2)2CH3] were synthesized by routine methods, while further examples of the series trans-PdX (C = CR)(PMe3)2 [5, 7, 8, 10, X = Br, R = SiMe3, CMe3, (CH2)2CH3, Ph; 7, 9, 11, X - I, R = SiMe3, SiPh3, OEt] and trans-PdX (C-CR)(PPh3)2 (12-14, X I,R = SiMe3, CMe3, CH2OH) were obtained by oxidative addition of 1-halogeno-1-alkynes to PdL4 (L = PMe3, PPh3). Just above the melting point or decomposition point 5 7 are transformed by oxidative trimerization of the alkynyl groups to give enediynyl complexes trans-PdX[C(C = CR) -C(C = CR)R](PMe3)2 (15, 16, R = SiMe3, X = Br, I; 17, X Br, R = CMe3). According to an X-ray structure analysis 17 has E configuration.
