Isoxazole group directed Rh(iii)-catalyzed alkynylation using TIPS-EBX†
A highly effective isoxazole directed ortho C–H alkynylation has been developed. Rhodium(iii) catalyzed direct di-(and/or mono) alkynylation using a hypervalent iodine reagent (TIPS-EBX) is reported. The reaction proceeds with a wide substrate scope under benign conditions. Preliminary mechanistic studies support this chelation assisted C–H alkynylation.
