Selenoacetals as well as mixed (O,Se) acetals react with lithium areni
des and produce, besides lithium selenolates, alpha-selenoalkyllithium
s or alpha-alkoxyalkyllithiums respectively. We Look advantage of thes
e reactions as well as of the ones involving the synthesis of alkyllit
hiums from selenides to propose an original method for geminal di-ally
lation of the carbonyl group of aldehydes and ketones.
