The synthesis and structural characterisation of phosphine-substituted alkynylboronates is reported. A P(III)-centred alkynylboronate (2) was prepared that showed little evidence for the conjugation of the P-lone pair to the boron via the alkyne π-s

The in situ generation of alkynyldifluoroboranes in the presence of N-heterocycle substituted tetrazines provides a convenient and direct method for the synthesis of pyridazine difluoroboranes. The reactions proceed in 10 min under ambient conditions

The aza-Diels–Alder cycloaddition of 1,2,4-triazines with alkynes offers a rapid and convenient method for the synthesis of highly substituted pyridines, but often requires harsh conditions and long reaction times. The present study offers a soluti

A concise synthesis of three members of the withasomnine family of natural products is reported. The synthesis features a regioselective sydnone–alkynylboronate cycloaddition followed by Suzuki cross coupling and silyl group removal, and marks the
