摘要:Treatment Of The Dithiolane Derivative Of An Ol-Carboxyethyl Benzaldehyde With Lda At-78 Degreesc Smoothly Produced The Thiothionophthalic Anhydride. The Mechanism Is Proposed To Involve Loss Of Ethene And Attack Of An Intermediate Dithiocarboxylate Onto The Ester. Heating The Thiothionophthalic An Hydride Gave The 3,3'-Bithiophthalide.
