Modular synthesis and photophysical and electrochemical properties of 2,3,5,6-tetraaryl-substituted benzo[1,2-b:5,4-b′]difurans

We developed a versatile synthesis of tetraaryl-substituted benzo[1,2-b:5,4-b′]difurans (m-BDFs) via a zinc-mediated intramolecular double cyclization reaction of 4,6-bis(phenylethynyl)-1,3-benzenediol, followed by a palladium-catalyzed cross-coupling rea

Palladium-catalyzed double annulations to construct multisubstituted benzodifurans

(Chemical Equation Presented) Efficient synthetic routes to construct multisubstituted benzo[1,2-b:5,4-b′]difurans and benzo[1,2-b:4,5-b′] difurans from bis(allyloxy)bis(alkynyl)benzenes or bis(alkynyl)dihydroxybenzenes and allylic halides utilizing palla

α-Heterosubstituted Phosphonate Carbanions. 11. Benzoins via an Acyl Anion Equivalent. Novel One-Pot Preparation of Benzofurans via Benzoins Using Hydriodic Acid

Diethyl 1-(trimethylsiloxy)-1-phenylmethanephosphonate carbanion 2 is introduced as a novel acyl anion equivalent.When 2 reacts with aldehydes or ketones, a 1,4 oxygen-oxygen silicon migration with subsequent loss of diethyl lithium phosphite is observed.An efficient method utilizing 2 for the preparation of otherwise difficultly obtainable substituted benzoins is presented.Also a novel one-pot method which offers a facile entry into the 2-phenylbenzofuran ring system from 2 via benzoin intermediates using hydriodic acid was developed.
