Metal-catalyzed hydrofunctionalization of alkenes offers the  potential to control the regioselectivity, diastereoselectivity,\cite{doi:10.1021/ja0477773} diastereoselectivity,\cite{Qian_Han_Widenhoefer_2004}  and enantioselectivity of the addition process and to form  products from readily accessible starting materials without the  formation of waste. Metal-catalyzed hydrofunctionalizations also
