摘要: Abstract The relative positions of the R and R′ substituents in “lactone” complexes, Co2(CO)7(RR′C4O2) (μ2-carbonyl-μ2-spiro-[2,3-substituted-2-butene-4- olide-4-ylidene]-bis[tricarbonylcobalt][CoCo] derivatives) was studied spectroscopically. It found that formation these complexes is stereoselective controlled by bulk R′.
