CuBr2-catalyzed alkylation of furans with a broad scope of benzyl alcohols and benzaldehydes is reported. Reaction proceeds efficiently under mild reaction conditions requiring no inert atmosphere or other precautions. Moreover, it is shown that CuBr2 catalyzes domino reactions of furans with benzyl alcohols or benzaldehydes bearing a nucleophilic moiety in the ortho-position. These protocols offer a

In the present study, we propose a general synthetic strategy toward potential push-pull chromophores containing furan, benzofuran, pyrrole and indole π-spacers based on the reactivity of substituted furans that act as nucleophilic or electrophilic relays. The results suggest that the strategy could be employed for the design of potential dyes for further studies in organic solar cells or dye-sensitized
