A technique for high recoveries from vacuum distillations

Abstract

Recebido em 30/6/06; aceito em 28/9/06; publicado na web em 27/4/07The design and use of a novel apparatus for a variant of vacuum distillation is described. Relative to a conventional device, the apparatus/technique described permits superior recovery of multigram quantities of moderately volatile liquids from vacuum distillations.

α-Benzoyloxylation of dimethyl trisulfide and a novel reaction of the resultant trisulfide benzoate

“…Preparation of 1 followed up with bundled column chromatography and reduced pressure distillation (4) provided material of satisfactory purity, albeit in somewhat reduced yield (19%).…”
