Regioselective bromomethylation of 1,2-dialkylbenzenes
This paper describes a systematic exploration of the regioselective bromomethylation of 1,2-dialkylbenzenes as a function of the reaction temperature and the chain length of the alkyl groups. At both 80 and 110 °C, bromomethyl groups can be introduced into the 4 and 5 positions of 1,2-dialkylbenzenes with high selectivity when the alkyl chains consist of two or more carbon atoms.

METAL COMPLEXES IN ORGANIC SYNTHESIS. VIII. ALLYLIC ALCOHOLS AS STARTING MATERIALS IN PALLADIUM-CATALYZED WITTIG-TYPE OLEFINIZATIONS.
Allylic alcohols, aldehydes, and triphenylphosphine participate in a one-pot process catalyzed by palladium, which is formally equivalent to the Wittig olefinization. It can be applied to both aliphatic and aromatic aldehydes. The resulting olefins which appear as mixtures of stereoisomers were fully hydrogenated. Two different mechanisms can account for the observed results.
