A new piece in the puzzle. Hydrido(alkoxo) complexes of late transition metals have often been postulated as intermediates or transition states in the catalytic hydrogenation of carbonyl compounds and catalytic hydrogen transfer reactions. Here the facile oxidative addition of the O-H bonds of alcohol and water to iridium(I) complexes of peraryldiphosphanes [Eq. (a)] is reported and the resulting complexes are described. R=H, Me.
难题中的新拼图。后过渡金属的氢(烷氧基)配合物常被假定为羰基化合物催化氢化反应和催化氢转移反应中的中间体或过渡态。本文报道了醇和水的O-H键与过芳基二膦铱(I)配合物的 facile 氧化加成反应[方程式(a)],并对所得配合物进行了描述。R = H,Me。
