The reaction of cyclopropylmethylstannane C3H5CH2SnBu3 (1) with α-iodocarbonyl compounds R1R2C(I)COX (2) in the presence of either InBr3 or InCl3 gave the C-C coupling products, 2-cyclopropylethyl carbonyls C3H5CH2CR1R2COX (3; R1, R2 = H, Me; X = PhO, PhCH2O, CH2:CHCH2O, tBuO, Et2N, Ph; R1R2C(I)COX = 3-iodo-γ-butyrolactone). Various types of iodocarbonyl compounds such as esters, amides, and ketones were applied to this system to afford the corresponding compounds 3. The reaction mechanism comprises transmetalation between cyclopropylmethylstannane and indium halides, providing 3-butenylindium dihalide and di-3-butenylindium halide, as confirmed by NMR spectroscopy. The reactivity of di-3-butenylindium halide was greater than that of monobutenyl species. The active species, di-3-butenylindium halide, was stabilized by complexation using DPPE, and its structure was analyzed using x-ray crystallog. The solid state of the complex shows a linear structure with a core (-Cl-In-Cl-In-P-C-C-P-In-)n with five-coordinated indium centers. The reaction between 1 and 2, mediated by indium halides, proceeded in a radical manner, regenerating after recyclization of 6-oxo-1-indiohex-3-yl radical the initial cyclopropylmethyl moiety. The in situ-generated alkylindium species and a small amount of oxygen, which can be supplied by atm. air, initiated the radical reaction.
