A SIMPLE AND COST EFFECTIVE SYNTHESIS OF 2-CYCLOPENTADIENYLIDEN-1,3-DIOXOLANE

摘要

A highly efficient preparation of 2-cyclopentadienyliden-1,3-dioxolane from cyclopentadiene and 2-chloroethyl chloroformate has been achieved. Reaction of two equivalents of sodium cyclopentadienide and KOH with 2-chloroethyl chloroformate at 0.1 M produce the highest yield of this fulvene. [References: 17]
