The action of phenyllithium on (bromomethyl)triphenylphosphonium bromide results in a nearly equimolar mixture of triphenylphosphinebromomethylene (formal H÷ abstraction) and triphenylphosphinemethylene (formal Br÷ abstraction). With (iodomethyl)triphenylphosphonium iodide a mixture of triphenylphosphineiodomethylene and triphenylphosphinemethylene is formed in which the latter is favored by a factor

A novel chlorinatingreagent with a high concentration of HCl has enabled the highly regioselective hydrochlorination of unactivated alkynes using a commercial nanogold catalyst. No overchlorination or hydration products were formed, and various functional groups were tolerated. This hydrochlorination method could be conducted under open air.
