HETEROANNULATION OF ALPHA,BETA-UNSATURATED CARBENE COMPLEXES - [3-ALKYNYL)TUNGSTEN CARBENE COMPLEXES WITH 1,3-THIAZOLIUM-4-OLATES(2] DIPOLAR CYCLOADDITION OF METHOXY(ALPHA,BETA)
Iy. Jung et al., HETEROANNULATION OF ALPHA,BETA-UNSATURATED CARBENE COMPLEXES - [3-ALKYNYL)TUNGSTEN CARBENE COMPLEXES WITH 1,3-THIAZOLIUM-4-OLATES(2] DIPOLAR CYCLOADDITION OF METHOXY(ALPHA,BETA), Chemistry Letters, (5), 1994, pp. 859-862
A novel [3+2] dipolar cycloaddition of methoxy(alpha,beta-alkynyl)tung
sten carbene complexes with 1,3-thiazolium-4-olates, synthetic equival
ents of thiocarbonyl ylide affords methoxy(thienyl)tungsten carbene co
mplexes or methoxy(pyridyl)tungsten carbene complexes depending on the
electronic nature of a substituent at N-3 on the 1,3-thiazole nucleus
.
