摘要
The reaction of 2-, 3- or 4-chlorobenzyl chlorides (1a-c) with an excess of lithium and a catalytic amount of DTBB (7 mol%) in the presence of different electrophiles [(PrCHO)-C-i, Bu(t)CHO, Et(2)CO(1) (CH2)(5)CO, PhCOMe, Me(3)SiCl] in THF at -50 degrees C leads after hydrolysis with water, to the expected dioles or disilylated compounds 2aa-2cf.
