Heteroatom containing compounds have attracted significant interest amoung synthetic and medicinal chemists over the years,because they are the key intermediate of natural products.For their construction,the importance of metal catalyzed intra- and intermolecular heterofunctionalizaion has been widely recognized,and much effort has been done toward its exploitation.Amoung them,the transformation was drastically developed by a strong pi-acidity of noble metal complexes,which resulted in an incredible effect on the addition of heteroatom functions to alkyne moieties.However,they have been used mostly for alkynes,not for simple olefins.Moreover,their procedures require loading of the expensive catalysts,high temperature,and long reaction time.Therefore,the development of the more practical catalystic system is desired.
