functionalized alkynes o-RC⋮C(C6H4)NO2 (R = H or alkyl) formally insert into two iridium hydrides, during which O-transfer of the nitrogroup into the C⋮C bond of o-RC⋮C(C6H4)NO2 is observed. For the terminal alkyne with R = H, iridium(III) nitroso complexes were isolated. For internal alkynes with R = Me or nPr, iridium hydride anthranil complexes were obtained as a result of O-transfer with a different regiochemistry
官能化的炔烃o -RC⋮C(C 6 H 4)NO 2(R = H或烷基)正式插入两个氢化铱中,在此过程中,硝基将O转移至o -RC the的C⋮C键中观察到C(C 6 H 4)NO 2。对于R = H的末端炔烃,可分离出铱(III)亚硝基配合物。对于R = Me或n Pr的内部炔烃,由于O-转移和不同的区域化学反应,获得了氢化铱蒽蒽配合物。提出了这些转化的机制,包括以前未知的从硝基到RC⋮C键的O转移步骤。
