The kinetics of the alkylation of the alkali-metal of triphenylmethane, fluorene, 1,3-diphenylindene, fluoradene, 9-methoxycarbonylfluorene, and 9-cyanofluorene by 1-halogenoalkanes with the general formula CH3(CH2)nX, where X = Cl, Br, and I and n varies between 0 and 5, were investigated in solvents of the ether type and in dipolar aprotic solvents.It was established that the rate constant for the alkylation of the carbanions decreases with increase in n from 0 to 2.The rate constant increases with further increase in the length of the alkyl chain.The observedextremal dependence of the reaction rate on n is due to the dynamic effects of the hydrocarbon chain.
