An efficient and simple synthesis of novel trisubstituted 1H-pyrroles 4a-qvia 1,3-dipolar cycloaddition of Δ3-trifluoromethyloxazolones 2a-d with both chromium and tungsten alkynyl Fischercarbenecomplexes (1a-h) is described. An unexpected and unreported -CF3 group elimination process was observed in the pyrrole structure. Our experimental and theoretical data suggested that the metal fragment may

Pyrrole polyfunctionalized core is obtained from Fischer alkynyl carbenes and oxazolones and used to obtain highly functionalized symmetric BODIPYs with modulating optoelectronic properties.
