Alkynylboron compounds in organic synthesis
Alkynylboron compounds, consisting of alkynyl and boron moieties, can be categorized according to the substituents on the boron atom, such as alkynylboranes, -boronates, and -borates. In this review, the synthesis and reactions of alkynylboron compounds are systematically introduced. Alkynylpinacolatoboranes and alkynyltrifluoroborates are the most widely utilized classes in organic reactions, owing to their stability and ease of handling. Other alkynylboron compounds have also been developed as convenient substrates for various organic reactions. Thanks to the dedication of many chemists in this field, great advances of facile synthesis and wide utilization of alkynylboron compounds have been made with these versatile building blocks for diverse structures in organic synthesis. 2012 Elsevier B.V.
