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.
