WebMay 7, 2007 · We examined the Pd-catalyzed heteroannulation of 2-haloamines with internal alkynes under phosphine-free conditions. The thiopseudourea palladium(II) complex (5) found to be an efficient catalyst for the Pd induced heteroannulation. Achieved high turnover number for the heteroannulation reactions of internal alkynes with 2-iodoaniline.
