斯克内克塔迪，纽约。本文研究了1、2、2个配合物作为烯烃氢硅化反应的催化剂。发现硅氢化和异构化反应的相对重要性取决于所用硅烷的性质。发现铂的烷基膦配合物与三烷基硅烷反应生成相应的铂填充氢化物。虽然没有发现形成稳定的I 'l - Si键的证据，但发现铱{1)的磷化氢配合物可以切割各种硅氢化物，在其配位球中保留硅和氢化物碎片。根据已知的d ‘ ’金属配合物的化学性质，提出了一种与配位催化氢化反应非常相似的烯烃氢化反应机理。
Schenectady, New York. Received March 12, 1964 l,/atiuum (II) and rhodium (I) olefin complexes have been studied as catalysts for the hydrosilation of olefins. The relative importance of hydrosilation and isomerization reactions was found to be dependent on the nature of the silane used. Alkyl phosphine complexes of platinumfjl) were found to undergo reaction with trialkylsilanes to produce the corresponding platinumfill) hydride. Al-though no evidence was found for the formation of stable I’l Si bonds, a phosphine complex of iridium {l) was found to cleave a variety of silicon hydrides, retaining both the silicon and the hydride fragments in its coor-dination sphere. On the basis of the known chemistry of d" metal complexes, a mechanism is suggested for the coordination-catalyzed hydrosilation of olefins which is very similar to that proposed for coordination-catalyzed hydrogenation reactions.
