Trithioorthoesters and Tetrathioorthocarbonates as RC3+ and C4+ Synthons. Nickel-Catalyzed Alkylative Olefination of Trithioorthoesters and Tetrathioorthocarbonates
نویسندگان
چکیده
NiCl2(PPh3)2-catalyzed alkylative olefinations of trithioorthoesters and te tra th ioortho carbonates give the corresponding substituted alkenes. A liphatic C -S bonds in these sub strates can be activated in the nickel-catalyzed cross coupling reaction leading to ca rb o n carbon bond form ation. This reaction can be considered as using trithioorthoesters and te tra th ioorthocarbonate as R3C3+ and C4+ synthons.

متن کاملRhodium(iii)-catalyzed ortho-olefination of aryl phosphonates.
Rhodium(iii)-catalyzed C-H olefination of aryl phosphonic esters is reported for the first time. In this mild and efficient process, the phosphonic ester group is utilized successfully as a new directing group. In addition, mono-olefination for aryl phosphonates is observed using a phosphonic diamide directing group.
