摘要: Abstract [Bis[μ-[(2,3-butanedione dioximato)(2-)- O : O′ ]]tetrafluorodiborato(2-)- N,N′,N″,N‴ ]cobalt (COBF, 1 ) was used as a catalyst for the conversion of trans -1,2-dibromocyclohexane (DBCH) to cyclohexene and photoelectrochemical cyclisation 2-(4-bromobutyl)-2-cyclohexen-1-one (BBC) -1-decalone 2 in microemulsion. Voltammetry showed clear evidence catalytic behaviour bulk electrolysis larger turnover numbers both reactions when compared with same system using vitamin B 12a catalyst. For BBC, improved may result from relatively weak carbon–cobalt bond alkylcobalt intermediate , better partition into organic phase which reactant BBC resides.
