Herein, we report a visible-light-mediated hydroalkylation reaction of alkenes using easily available aldehydes as alkyl sources via bromo radical-promoted photoredox decarbonylation. This protocol provides an alternative entry to C(sp3)−C(sp3) bond formation and features considerable advantages including mild and clean reaction conditions, obviation for transition-metal catalyst, and good functional

Phenyllithium, -butyllithium, and -butyllithium were found to add to substituted acrylanilide anions to give the 1,4-addition products in fair to good yields.
In the presence of 3 equivalents of MeLi, various Grignard reagents reacted with secondary α,β-unsaturated amides and α,β-unsaturated carboxylic acids to give the corresponding Michael adducts in g...
