Efficient allylation of carbonyl compounds with allyl chlorides in water [PDF]

ARKIVOC, 2004
A novel mediation system, Zn-InCl3 (cat.)/NH4Cl was employed in the Barbier–type allylation. As a result, the allylation with allyl chloride in water took place smoothly under mild conditions. Various aldehydes and even ketones could be employed to afford the corresponding alcohols in high yields.

Design, synthesis, and SAR study of isopropoxy allylbenzene derivatives as 15-lipoxygenase inhibitors [PDF]

Iranian Journal of Basic Medical Sciences, 2020
Objective(s): Allylbenzenes have been recently developed as inhibitors of lipoxygenases. They decrease peroxidation activity via mimicking 1,4-unsaturated bonds of fatty acids by their allyl portion.

An infrared investigation of the catalyst formation in the system Ni(acac)2, C3H4, (iBu)3AL for propadiene polymerization [PDF]

, 1977
The catalyst formation in the system Ni(acac)2, C3H4, (iBu)3Al was investigated by means of infrared spectroscopy. It was found that the Al(acac)3 and (iBu)2Al(acac) formed are both by-products of catalyst formation without a catalytic activity.
