Abstract
Official abstract text for this publication.
Methods for synthesizing deuterated vinylpyridine compounds of the Formula (1), wherein the method includes: (i) deuterating an acyl pyridine of the Formula (2) in the presence of a metal catalyst and D 2 O, wherein the metal catalyst is active for hydrogen exchange in water, to produce a deuterated acyl compound of Formula (3); (ii) reducing the compound of Formula (3) with a deuterated reducing agent to convert the acyl group to an alcohol group, and (iii) dehydrating the compound produced in step (ii) with a dehydrating agent to afford the vinylpyridine compound of Formula (1). The resulting deuterated vinylpyridine compounds are also described.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for synthesizing deuterated vinylpyridine compounds of the formula: wherein one of A 2 , A 3 , A 4 , A 5 , and A 6 is a vinyl group of the formula: wherein R 1 and R 2 are each independently either a deuterium atom or a perdeuterat…
