 Title    Kernresonanzspektroskopische Untersuchungen OH-, 13 C-, 31 P-, 195 Pt-NMR) an Alkinyl-Komplexen von Pt n , Pd n und Ni" Nuclear Magnetic Resonance ^H-, 13 C-, 31 P-, 195 Pt-NMR)-Studies of Alkynyl Derivatives of Pt 11 , Pd 11 and Ni 11  
 Abstract    The NMR parameters (X H, 13 C, 31 P, 195 Pt) of compounds of the type eis-and trans-[M(C=C-R)2(PR'3)2] (M = Ni, Pd, Pt) are reported. The chemical shifts <5 13 C (M-C=C; R) and <5 195 Pt (together with UV data) indicate the presence of jz-backbonding from the metal into the orbitals. This also explains some unusual features of the coupling constants J(= 13 C 1 H), J(i 3 C= 13 C) and J(195 Pt 13 C=). The NMR parameters reflect an increase in the amount of yr-backbonding for Pt < Pd < Ni.
