Other typical Mn(III)-based reactions of various β-diketo esters 4a–e, 2,4-pentanedione (6a), malonic acid (6b), and diethyl malonate (6c) with 1,1-diarylthenes 2a-d were also investigated in a similar acetic acid–formic acid mixed solvent and it was recognized that the reaction rate was accelerated and the product yield increased., http://www.tandfonline.com/doi/full/10.1080/00397911.2015.1049618}, pages = {1807--1816}, title = {Advanced Synthesis of Dihydrofurans.
