Scope and Limitation of the Reaction of Benzocycloalkanone Oximes with Lawesson's Reagents

Abstract

1,3,2,4-Dithiadiphosphetane-2,4-disulfide and its p-phenoxy derivatives react with 2-indanone-, 1-indanone-oxime, and tetralone oxime at different reaction temperatures to give 1,3,2-dithiaphosphetane-2-sulfide, dimeric compounds, 1-thioxo-1H-inden- phosphinodithioic acid, and 1,3,5,2-trithiaphosphorine. Compatible analytical and spectroscopic results were obtained for all the new compounds.

Keywords:

• 2-Indanone
• 1-indanone-oximes
