A summary of recent interstellar molecular line work will be presented. Transitions of the follwing molecules have been detected in Sgr B2: Vinylcyanide, H2C2HCN, formic acid, HCOOH, dimethyl ether (CH3)2O and isotopically labelled cyanoacetylene — 13C,HC13CCN and HCC13CN. The data on cyanoacetylene give an upper limit to the abundance ratio 12C/13C of 36 ± 5. A short discussion of the interstellar chemistry leads to the conclusion that hydrocarbons such as acetylene, HCCH, ethylen, H2CCH2 and ethane H3CCH3 should be present in interstellar clouds.
