Solid Liquid

Under microwave-activation polyethylene glycol bound 4-iodobenzoic acid could be readily reacted with various terminal alkynes in excellent yields and purity using polyethylene glycol (PEG) as a solid-liquid phase-transfer catalyst and polymer support; the cleavage could be dramatically accelerated under microwave activation.

In this paper, we report the successful synthesis of new 2-phenyl-3-substituted furo/thieno[2,3-b]quinoxaline derivatives from 2-chloro-3-methoxyquinoxaline and 2-chloro-3-(methylthio)quinoxaline by a three-step approach.
