Reductive arylation of electron-deficient olefins: 4-(4-chlorophenyl)butan-2-one
No full textBenzenediazonium compds. 4-RC6H4N2+ (R = H, Br, Cl, OMe, MeCO) were treated with R1CR2:CHR3 (R1 = H, Me, CHMe2, CMe3, Ph; R2 = H, Me; R3 = COMe, CHO, cyano, CO2H, CO2Et) and TiCl3 to yield reductive arylation products I. Thus, CH2:CHCOMe was added to TiCl3 in DMF under N, 4-ClC6H4N2+ Cl- was introduced slowly, and the mixt. was stirred to give 4-ClC6H4CH2CH2COMe - Ripubblicato in: Organic Syntheses, Coll.
