Unstable N-alkoxycarbonyl quaternary salts of axaaromatics were trapped in sifu by bis(tributylstannyl)acetylene followed by the treatment with trifluoroacetic acid to give 2-ethynyl addocts in good yields. The same compounds were obtained only ia low yields when ethynyluibutyltin was used as a nucl
