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.

Gold-catalysed allylic alkylation of aromatic and heteroaromatic compounds with allylic alcohols
Organic & Biomolecular Chemistry, 2008Friedel-Crafts allylic alkylation of a wide variety of aromatic and heteroaromatic compounds with allylic alcohols catalysed by AuCl(3) (5 mol%) under mild conditions at room temperature was accomplished in good to excellent yields (up to 99%) and regioselectivity.

This chapter focuses on allyl alcohols, which are renowned for their ease of oxidation. It refers to manganese dioxide, which is highly effective for bringing about the oxidation of primary allylic alcohols to the αβ-unsaturated aldehydes. It also describes a highly-selective oxidation of allylic alcohols that involves epoxidation of the carbon-carbon ...

Polymerization of allyl compounds. IV. Emulsion polymerization of allyl acetate
Journal of Polymer Science, 1948AbstractThe emulsion polymerization of allyl acetate yields a polymer of the same average molecular weight as is obtained in bulk polymerization. The decomposition of potassimn persulfate is of the first order but is greatly accelerated by the presence of allyl acetate or of ethyl acetate.
