Preparation and Reaction of Cyclic Oxalate of Diols

cis-Perhydro-1,4-benzodioxin-2,3-dione

“…The title compound, (I), is the major product of the reaction of oxalyl chloride and cis-1,2-cyclohexanediol in the presence of triethylamine; the corresponding cyclic carbonate forms as the minor product (Itaya & Iida, 1994;Itaya et al, 2002). Despite signi®cant study in the literature (Lloyd et al, 1975;Kim et al, 1991;Itaya & Iida, 1994;Itaya et al, 2002), a crystallographic study has never been published. We report the structure of (I) here.…”
