Published: February 2021

A unique deoxygenative cyclodimerization of alkynyl 1,2-diketones facilitated by Ti(OPr) is achieved, affording a series of highly functionalized furan products. An unusual C-C bond and C═O bond cleavage of the substrates is observed, and Ti(OPr) plays triplicate roles in the reaction. Furthermore, the products show uncommon fluorescent emission in the solid state, indicating the potential practical applications of this work.
