• 2-Alkynes are metallated almost exclusively at the terminal position by t-BuLi + TMEDA in ether. Subsequent reaction with, e.g. TMS chloride gives propargylic silanes: Synthesis, 111 (1984).

• On heating under pressure with norbornene and CO in the presence of Dodecacarbonyltriruthenium, 10507, alkynes undergo aromatization to give condensed hydroquinones: Organometallics, 17, 766 (1998):
