The ReH(7)(PPh(3))(2)-catalyzed addition of carbonyl compounds to the carbon-nitrogen bond of nitriles proceeds efficiently and selectively to give the corresponding (Z)-enamines, which are important synthetic intermediates. The key step of the reaction is the chemoselective alpha-C-H activation of carbonyl compounds induced by the alpha-heteroatom effect in the presence of nitriles.
ReH(7)(PPh(3))(2)-催化将羰基化合物添加到腈的碳-氮键上,高效且有选择性地得到相应的 (Z)-烯胺,它们是重要的合成中间体。该反应的关键步骤是在腈存在下由 α-杂原子效应诱导的羰基化合物的化学选择性 α-CH 活化。
