variance with the flexible 1′ derivative, the rigid bis-alkyne 1 reacts smoothly to give the corresponding cyclopalladate complexes [PdC4(COOMe)2(Ph)2(LL′)] (3). The rates of reaction were determined and the X-ray diffraction structure of the complex [PdC4(COOMe)2(Ph)2(HNSPh )] (3A) is reported. The reactivity of the complexes [PdC4(COOMe)2(Ph)2(LL′)] (LL′ = HNSPh (3A), BiPy (3B), DPPE (3C)) was studied
