S. Dare et al., CHEMOSELECTIVE, REGIOSELECTIVE AND STEREOSELECTIVE ADDITION OF NITRILE OXIDES TO COBALT-COORDINATED 1,3-ENYNES, Tetrahedron letters, 37(25), 1996, pp. 4341-4344
Unlike the frequently unselective reactions of 1,3-enynes with 1,3-dip
oles, nitrile oxides add chemo-, regio- and stereoselectively to the f
ree double bond of (1,3-enyne)Co-2(CO)(6) complexes to provide 5-alkyn
yl-2-oxazoline derivatives in moderate to excellent yield. Copyright (
