Solvent-Mediated Allylation of Carbonyl Compounds with Allylic Stannanes
The Journal of Organic Chemistry, 1997Methanol promotes the addition of allyltrimethylstannane (1a) to isobutyraldehyde (2a, 30 degrees C) yielding the corresponding homoallylic alcohol (3a), without the necessity for added catalyst. The corresponding reaction of aldehydes 2a-eor activated ketone 2f with tetraallyltin (1b, 0.25 equiv) is substantially faster and proceeds in high yield (81 ...

Journal of Organometallic Chemistry, 1980
Abstract Physical measurements, primarily high resolution nuclear magnetic resonance, support the contention that the allyl alkali metal compounds are ionic in solution but exist as intimate ion pairs or clusters. The sodium, potassium, rubidium and cesium compounds, when first formed at low temperatures, are in a more freely rotating form.

Iron-Catalyzed Electrochemical Allylation of Carbonyl Compounds by Allylic Acetates
The Journal of Organic Chemistry, 2003Homoallylic alcohols were synthesized from aldehydes or ketones and allylic acetates, using an electrochemical process catalyzed by iron complexes. We first studied the reactivity of allyl acetate, using N,N-dimethylformamide (DMF) or acetonitrile (AN) as solvent, FeBr(2) as catalyst, and Fe as the sacrificial anode.

Polymerisation of Allyl Compounds
Russian Chemical Reviews, 1970The review deals with the advances in the theory of the formation of allyl polymers and their practical applications. Until recently there was only limited interest in allyl polymers because with the usual free-radical initiation allyl compounds polymerise with difficulty and yield polymers with a low molecular weight.
