The macrocyclic alkylnickel(II) complexes, RNi(tmc)+ (R = C2H5, C3H7, and CH2-c-C5H9; tmc = (1R,4R,8S,11S)-1,4,8,11-tetramethyl-1,4,8.11-tetraazacyclotetradecane), react with alkyl halides R'X (R'= CH3, C2H5, 1-C3H7, 2-C3H7, and PhCH2) in alkaline aqueous solutions, yielding combination and disproportionation products of R and R'.The reactivity of R'X increases in the order methyl . + 2-C3H7I -> 2-C3H7. + C2H5I in aqueous solution was determined by competition with V(H2O)62+.The value k2-PrI ca. 6E5 M-1s-1 is significantly higher than in aprotic solvents.
