Mild and Efficient Molybdenum-Mediated Pauson—Khand-Type Reaction. —
new version of the molybdenum-mediated title reaction is developed. It is based on
25- 063 A
the use of Mo(CO)3(DMF)3 as a highly reactive carbonyl-metal complex. Unlike the
traditional reactions, those in the paper described take place under very mild conditions
in the absence of any promoter. The scope of the intramolecular process is broad and
tolerates the presence of a wide variety of substituents and functional groups at the
1,6- and 1,7-enyne framework, including electron-withdrawing groups at the alkene
terminus. — (ADRIO*, J.; RODRIGUEZ RIVERO, M.; CARRETERO*, J. C.; Org.
