ruthenium hydride complexes are promising lead structures for the CH bondactivation and functionalization of aromatic compounds. In the present paper, the preparation and crystallographic characterisation of the first organometallic complexes bearing dihydrogen ligands and N-heterocycliccarbene ligands in the same coordination sphere are described. The mixed phosphine/carbenecomplex [(IMes)Ru(H)2(H2)2(PCy3)]
非经典氢化钌络合物是用于芳族化合物的CH键活化和功能化的有前途的铅结构。在本文中,描述了在同一配位域中带有二氢配体和N-杂环卡宾配体的第一有机金属配合物的制备和晶体学表征。膦/卡宾复合物[(IMes)Ru(H)2(H 2)2(PCy 3)](IMes = 1,3-dimesityl-1,3-dihydro-2 H -imidazol-2-ylidene; 3a)在CH键的分子间和分子内激活中显示出独特的反应模式。特别是复杂的3a可以在室温下快速而显着地选择性降解简单芳香化合物中sp 2 CH键的分子间活化。

effect” of the solvent methanol, deuterations of electron-rich aromatic systems can be carried out under mild acid catalysis and thus under far milder conditions than known so far. The exceptional functional group tolerance observed under the optimized conditions, which even includes highly acid-labile groups, results from a hitherto unexploited shifted selectivity in protonation, and enabled simple
