応用分野 · 2 件

使用Cerium(III) chloride heptahydrate can be used in the conversion of esters to allylsilanes.

一般的な説明Cerium(III) chloride heptahydrate is a mild Lewis acid. It participates in the allylation of aldehydes. Cerium(III) chloride heptahydrate in combination with sodium iodide supported on silica gel efficiently promotes Michael-type addition. Cerium(III) chloride heptahydrate in the presence of sodium iodide acts as an efficient catalyst for the Michael addition of 1,3-dicarbonyl compounds to α,β-unsaturated ketones and α,β-unsaturated aldehydes.
