Sažetak
Kinetic data are presented for the reaction of alkylchromium complexes (H2O)([14]aneN4)CrR2+ ([14]aneN4 = 1,4,8,11-tetraazacyclo-tetradecane) with Hg2+ via electrophilic substitution. The rate constants decrease in the order CH3 (1.1 × 106 mol-1 dm3 s-1) > C2H5 (7.7 × 102) > C3H7 (59) > 2-C3H7 (0.12) > CH2C(CH3)3 (0.0086). A series of meta and para substituted benzyl complexes obey a Ham-mett relationship with the reaction constant ρ = -1.66, consistent with electrophilic substitution at α-carbon.
