Careful investigation by Olah and Comisarowl of the reaction between dicarboxylic acid fluorides and+antimony pentafluoride showed that allcylene dioxodicarbonium ions (acyl dications) were not formed unless the acyl groups were insulated by at least three methylene groups. It was considered of int

## Abstract The conformation of some 2โ€ฯƒโ€1,3,2โ€dioxaphospholanes (ฯƒ=OAlkyl, CI) is studied. The determination of the ^2^__J__(POC) and ^3^__J__(POCC) coupling constants, which are influenced by the bulk of the alkoxy group, is a means of obtaining information about the rotation around the P๏ฃฟOR bond
