Nitration of phenylpropiolic acid derivatives ArC≡CX (X=CN, CO2Me) in HSO3F at −75...−50°C afforded mononitro compounds, for instance, m-O2NC6H4C≡CX. Vinyl type cations generated in HSO3F from methyl 3-arylpropiolates ArC+=CHCO2Me react along two pathways. The first among them results in formation of fluorosulfonates ArC(OSO2F)=CHCO2Me, and the second one after the attack of vinyl cation on the aryl moiety of the substrate affords a dimer that on nitration is converted into a nitro product with conserved triple bond.

A method of preparing conjugated alkynenitriles was developed from various aldehydes with CCl3CN and PPh3 in the presence of (BuLi)-Bu-t. The reaction proceeded via alpha-chlorovinyl nitrile as an intermediate without any side reactions such as chlorination of starting aldehydes. (c) 2007 Elsevier Ltd. All rights reserved.
