Guidance literature:: With tert.-butyl lithium; In diethyl ether; an ethereal soln. of (p-FC6H4Me)Cr(CO)3 was treated with a 3-fold excess of t-BuLi at -78°C under N2 followed by addn. of 5-fold excess of ClCOOMe, soln. was stirred for 1 h at -78°C and allowed to warm to room temp.; solvent was removed in vacuo, residue was taken up in benzene, flushed through a short column of SiO2, chromd. on a SiO2 column (eluent EtOAc-hexane); elem. anal. for bis-Cr complex, mono-Cr complex was identified only on the basis of its mass spectrum;
