Highly active phosphite gold(I) catalysts for intramolecular hydroalkoxylation, enyne cyclization and furanyne cyclization.
New and highly active mononuclear phosphite gold(I) catalysts are described. Turn-over numbers up to 37,000 for the furan-yne reaction and up to 28,000,000 for the two-fold hydroalkoxylation of alkynes are reported.
