Microscale Synthesis of Tributyl Arsenite

Abstract
The most common ways to prepare arsenite esters make use of the reaction of arsenic trichloride with either sodium alkoxides, or alcohols in the presence of tertiary amines. Arsenic trichloride is a moisture-sensitive product for which the recently reported synthesis - direct reaction of arsenic(III) oxide with excess thionyl chloride - is not as simple as it appears, because the excess thionyl chloride is difficult to remove. Here we describe a simple synthesis for tributyl arsenite that makes use of the reaction of arsenic(III) oxide with butanol.
