oxidative cleavage of the metal–metal singly-bonded diruthenium(I) precursor [Ru2(CO)4(CH3CN)6(OTf)2] with 1,8-naphthyridine functionalized NHC precursor 1-benzyl-3-(5,7-dimethyl-1,8-naphthyrid-2-yl)imidazolium bromide (BIN·HBr) at room temperature. Compound 1 catalyzes transfer hydrogenation of ketones to alcohols, and carbene-transfer from ethyl diazoacetate to a variety of substrates. It is shown to
的单核钌(II)-N杂环卡宾(NHC)络合物的[Ru II(CO)2(κ 2 C,N-BIN)(H 2 O)BR] [光学传递函数](OTF =三氟甲磺酸)(1)已通过将金属-金属单键合的二钌(I)前体[Ru 2(CO)4(CH 3 CN)6(OTf)2 ]与1,8-萘啶官能化的NHC进行氧化裂解以高收率合成在室温下将前体1-苄基-3-(5,7-二甲基-1,8-萘基-2-基)溴化咪唑鎓(BIN·HBr)制成。化合物1催化将酮加氢转移成醇,以及将卡宾从重氮乙酸乙酯转移到各种底物上。它被证明是将卡宾插入醇和胺的O–H和N–H键的出色催化剂。
