Bridgehead acid chlorides 1a and 1b react with activated alkenes 2 in the presence of a catalytic amount of palladium and 1 equiv of a tertiary amine. The reaction proceeds regio- and stereoselectively at the terminal carbon atoms to yield acylated alkenes 3 with E-configuration.

Aryl-substituted alkenes of the adamantane series, 1-[(Z,E)-3-phenylprop-2-en-1-yl]adamantane and 1-[(Z)-3-phenylprop-1-en-1-yl]adamantane, have been synthesized by the Wittig reaction. Their allylic bromination involves two concurrent reactions, radical substitution and raical addition. The different chemical behaviors of the aryl-substituted alkenes have been demonstrated in the Ritter reaction.

A carbonylative Mizoroki–Heck reaction using alkyl iodides was achieved with a Pd/photoirradiation system using DBU as a base. In this reaction, alkyl radicals were formed from alkyl iodides via single-electrontransfer (SET) and then underwent a sequential addition to CO and alkenes to give β-keto radicals. It is proposed that DBU would abstract a proton α to carbonyl to form radical anions, giving

Optically active beta-substituted ketones of up to 94% e.e. were synthesized by the enantioselective conjugate addition of diethylzinc to enones in the presence of either a catalytic or stoichiometric amount of chiral beta-aminoalcohol.
