Monoselenoacetals can be synthesized from the reaction of acetals with diisobutylaluminium benzeneselenolate (i-Bu2AlSePh) under mild conditions in good yields. Diselenoacetals are also obtained by treating acetals with large excess amount of i-Bu2AlSePh.
1-Alkoxyalkyl radicals [R1R2(OR3)C·], which were generated from 1-alkoxy-1-(phenylseleno)alkanes [R1R2C(OR3)SePh] and n-Bu3SnH in the precence of AIBN, participate effectively in intermolecular add...
