dibutenylindium species. The bulky substituent on a cyclopropyl ring selectively afforded the monobutenylindium species, which allowed the isolation and X-ray structural analysis of the monobutenylindium complex. In an investigation of the generated substituted butenylindium species, we found that indium halide interacted with the less sterically hindered carbon−carbon bond of the cyclopropyl ring during transmetalation

by-product to be inert to the reaction system. In addition, the transmetalation of a (cyclopropylmethyl)stannane and InBr3 provided the dibutenylindium bromide as a single product, which smoothly coupled with the unstable phosphonyl radical species from the iodo phosphorus compound. A photochemical method (UV irradiation) was also applied and accelerated the coupling reaction. The cyclopropylmethylated
