Trans hydrido

This solution is transferred to a solution of the trans-hydrido(methanol)bis(triethylphosphino)platinum(II) cation, Solution A, prepared as described in Section A. Stirring is continued for 16 to 18 h while the... 

Preparing trans-hydrido-alkyls or -aryls of platinum(II) does not require prior isolation of a hydroxo complex. The main routes we have used are shown in Equations 9-11, and selected spectroscopic data, including some from the literature, are in Table IV. 

The trans hydrido ligands in /wendo-octahedral complexes Ta(H)2L(OAr)2X (L = PR3 X = Cl, OAr) are bent away from the sterically less-demanding ligand X towards the bulkier phosphorane ligand L (Scheme 29). Ab initio calculations indicate that this distortion arises form the relative 7r-acceptor ability of L relative to X.454... 

The compound trans-PdHCl[As(Bu-t)3]2 gives, at a slower rate, a mixture of cis and trans hydrido-bridged dinuclear Pd(II) complexes, [PdCH2C(Me)2As(Bu-t)2]2 (/ -H)2. 

Early in our investigation of 1, acetonitrile was used as a solvent for NMR studies. Surprisingly, this solvent reacted with 1 to form a trans-hydrido cyanomethyl complex of the type ... 

Earlier we noted that disubstituted acetylenes react with 1 to give TT-bonded complexes. Acetylene and monosubstituted acetylenes react to give trans-hydrido acetylide complexes (23). The DPPE complexes, 3, 4, and 5, also react with acetylenes to give trans-hydrido acetylide complexes (25,37). Iso-electronic hydrido cyanide complexes are obtained upon reaction with hydrogen cyanide. The reaction of HCN with Fe(DMPE)2H(CioH7) is the first reaction reported here (23) that proceeds by a mechanism different from those already discussed. The reaction, which is over essentially upon mixing, seems to involve electrophilic attack prior to loss of naphthalene. 

Trimethylsilane reacts with 1 to give a mixture of the cis- and trans-hydrido trimethylsilyl complexes. This reaction is of particular interest because trimethylsilane represents the only case in which we can be certain that there is no form of precoordination before attack to give the hydrido species. In all other cases—arenes, acetylenes, activated methyl groups, and others—there is some conceivable mode of coordination prior to the attack on the C-H bond...
