A unique deoxygenative cyclodimerization of alkynyl 1,2-diketones facilitated by Ti((OPr)-Pr-i) (4) has been achieved, resulting in a series of highly functionalized furan products. Unusual C-C and C=O bond cleavage of the substrates is observed, with Ti(OiPr)(4) playing triplicate roles in the reaction. Furthermore, the products exhibit uncommon fluorescent emission in the solid state, indicating potential practical applications of this work.
