Recent Literature
The reduction of a series of alkyl sulfonates to the corresponding hydrocarbons
was efficiently performed using a reducing system composed of CuCl2·2H2O,
an excess of lithium sand and a catalytic amount of 4,4′-di-tert-butylbiphenyl
(DTBB), in tetrahydrofuran at room temperature. The process was also applied to
enol and dienol triflates affording alkenes and dienes, respectively.
