Palladium-catalyzed cross-coupling of arylboric acids and sodium tetraphenylborate with aryl halides in aqueous solutions. Bumagin, N. A.; Bykov, V. V.; Beletskaya, I. P.. Mosk. Gos. Univ., Moscow, USSR. Doklady Akademii Nauk SSSR (1990), 315(5), 1133-6 [Chem.]. CODEN: DANKAS ISSN: 0002-3264. Journal written in Russian. CAN 115:158650 AN 1991:558650 CAPLUS
Abstract
Pd(OAc)2 and PdCl2 catalyzed the title reaction of 10 RX [R = m- and p-HOC6H4, o-, m- and p-HO2CC6H4, 4,3-HO(HO2C)C6H3; X = Br, iodo] with R1B(OH)2 [R1 = Ph, 4-FC6H4, 4-(4-pentylcyclohexyl)phenyl] and PhB(OEt)2 in aq. NaOH or Na2CO3 to give 39-99% RR1. Analogous reaction of these RX and RI (R = m- and p-O2NC6H4, p-HCOC6H4) with NaBPh4 gave 53-100% RPh, o-C6H4Br gave 69% o-BrC6H4Ph or 98% o-Ph2C6H4, depending the reactant ratio.
