variety of aryltin compounds and sodium tetraarylborates can be employed for Michael-type hydroarylation reactions of nitroalkenes to afford β-arylnitroalkanes in moderate to good yields in the presence of either LiCl, MgCl2, or CaCl2 and a catalytic amount of palladium(II) salt (0.05 molar amount) in acetic acid. Results show that 50–70% of aryl groups out of all in these arylcompounds can be transferred

A novel catalytic effect of bismuth(III) salts such as BiCl3, Bi2O3, and Bi(NO3)(3).5H(2)O has been disclosed in new palladium(II)-catalyzed Michael-type hydroarylation of nitroalkenes with aryltin compounds. The reaction is atom economical in the tin compounds and slightly fewer than four aryl groups of tetraaryltins can be transferred to the produces. (C) 2002 Elsevier Science Ltd. All rights reserved.
