โœฆ Synopsis

The reaction between CpFe(CO)21, hydroxy-or aminoalkynyl stannanes, and PdCI2(CH3CN)2 (8.0 tool. %) generates a reactive iron-alkynyl intermediate that reacts in situ with RCHO/BFyEt20 to yield an iron oxa-or azacarbeniums quantitatively, further producing oxygen-and nitrogen heterocycles in high yields after Me3NO-oxidation of these calbenium salts.

Palladium-Catalyzed Syntheses of Oxygen-and Nitrogen Heterocycles via Transmetalation of Functionalized Alkynyl Stannanes. -Hydroxy-and aminoalkynylstannanes undergo a Pd-catalyzed reaction with CpFe(CO) 2 I to generate a reactive iron-alkynyl intermediate which is trapped in situ by an aldehyde in
