Process for Producing a Fluorinated Alkene

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel process for producing fluorinated alkenes by selectively reducing certain fluorinated alkene compounds using organic hydride reducing agents, such as alanes (aluminum hydrides), gallanes (gallium hydrides), or boranes (boron hydrides), in a donor solvent. The process efficiently converts one type of fluorinated alkene to another with specific structural characteristics.

Patent Abstract

The invention refers to a process for producing a fluorinated alkene, in particular X1n—CFmCF═CH2 comprising the steps of a) providing a at least one fluorinated alkene of the general formula (I) X1n—CFmCF═CF2, wherein n is 0, 1, 2, 3; X1 is H, substituted or unsubstituted C1-C5 alkyl, m is 1, 2 or 3, preferably 2 or 3, in at least one donor solvent; b) adding at least one reducing agent selected from the group of organic aluminum hydrides (alanes), gallium hydrides (gallanes) or boron hydrides (boranes); and c) reacting the mixture of the fluorinated alkene according to formula (I) and the at least one reducing agent.
