This invention relates to a process of making aromatic compounds, products thereof and to a process of making benzoxaboroles. According to one aspect, the present invention provides a process of making an aromatic compound or derivative thereof comprising: reacting an alkynyl moiety containing an element selected from group 13 or 14 with a 2- pyrone moiety containing a Lewis base in the presence of a Lewis acid to form a six- membered ring fused with a five-membered ring. According to another aspect, the present invention provides compounds from the use of said method. In a further aspect, the present invention provides a process of making a benzoxaborole or a derivative of such a benzoxaborole comprising the steps of: a) reacting an alkynyl borate with a 2-pyrone moiety substituted with an amide in the presence of a Lewis acid to form an aromatic borane; b) reacting said borane with a reducing agent.

Simple as ABC: Alkynyl borane cycloadditions can be substrate‐directed to assemble aromatic difluoroboranes within an extremely mild and efficient reaction manifold compared to that of traditional methods (see scheme). The aromatic boranes are readily transformed into a range of useful products.
