Allene triazole derivatives were successfully synthesized for the first time through iron catalyzed regioselective triazole addition to tertiary propargylalcohols. The reaction proceeds under mild conditions, giving the desired allene-triazoles in good to excellent yields (up to 96%). The resulting allene-triazoles were confirmed by X-ray crystallography and indicated improved stability.

carbon of phenols. Our approach relies on the synthesis of a 1,5-dibromo-1,4-pentadiene precursor, which upon lithium–halogen exchange followed by treatment with carbonate esters results in a formal [5 + 1] cyclization to form the phenol product. Using this strategy, we have prepared 12 1-13C-labeled phenols, show proof-of-concept for the labeling of phenols with carbon-14, and demonstrate phenol synthesis
