| 値 | In this study, the atom transfer radical addition (ATRA) reaction of olefins RCH=CH2 (R = Bn, 3-methoxy-2-(methoxycarbonyl)-3-oxopropyl, hydroxymethyl, etc.) using bromomalonates R1C(C(O)R2)2Br (R1 = H, Me, n-Pr, 2-cyanoethyl; R2 = OMe, OEt, Ph, t-Bu) as halogen-bonding donors was developed. Using 4-phenylpyridine as the halogen-bonding acceptor, the desired reaction proceeded well under external irradiation of 380 nm light to furnish the corresponding ATRA reaction products RCH(Br)CH2C(C(O)R2)2R1. The ATRA reaction was effective in generating the corresponding products for a variety of olefins. Furthermore, the ATRA reaction was applicable to bulky ketones, substrates, and malonate esters. The intermediates of the reaction were identified and a plausible reaction mechanism was proposed. | |||||
