The first examples of essentially two-coordinate, monomeric zinc hydride complexes, LZnH (L = -N(Ar)(SiR3)) (Ar = C6H2{C(H)Ph2}2R'-2,6,4; R = Me, R' = Pr(i) (L'); R = Pr(i), R' = Me (L*); R = Pr(i), R' = Pr(i) (L(†))) have been prepared and shown by crystallographic studies to have near linear N-Zn-H fragments. The results of computational studies imply that any PhZn interactions in the compounds are weak at best. Preliminary reactivity studies reveal the compounds to be effective for the stoichiometric hydrozincation and catalytic hydrosilylation of carbonyl compounds.
基本上为二配位的单体氢化锌配合物LZnH（L = -N(Ar)(SiR3)）（Ar = C6H2{C(H)Ph2}2R'-2,6,4；R = 甲基，R' = 异丙基（L'）；R = 异丙基，R' = 甲基（L*）；R = 异丙基，R' = 异丙基（L(†)））的首批实例已被制备出来，并且晶体学研究表明其具有接近线性的N-Zn-H片段。计算研究结果表明，这些化合物中任何PhZn相互作用充其量都很微弱。初步反应性研究表明，这些化合物对于羰基化合物的化学计量氢化锌化反应和催化硅氢化反应是有效的。
