Simultaneous O-demethylation and hydrogen/deuterium exchange of aryl-methylethers can be obtained using 1-[ 2 H]-pyridinium hydrochloride as reagent at 2208C for 6 h. This reaction was applied to dextromethorphan and various non-steroidal antiinflammatory drugs.

## Abstract A regioregular poly[4′‐dodecyl‐3‐(1H,1H,2H,2H‐perfluorooctyl)‐2,2′‐bithiophene] (P3DDFT) with alternating alkyl and semifluoroalkyl side chains were synthesized. Short ethylene spacer between perfluorohexyl part and thiophene did not largely affect the absorption and emission properties
Two synthetic routes for deuterium labelling of 1,1,3,3-tetraethoxypropane, the precursor of the ubiquitous natural compound malondialdehyde, are described. In one scheme, deuterium is inc.orporated in ethyl vin 1 ether by metalation ing with $,,,. The conversion of the deuterated ether to monodeute
## Abstract **Summary:** The preparation of a new family of acrylic esters with a perfluorinated chain directly bonded to one or two conjugated triple bonds from 1H,1H,2H,2H‐perfluoro‐3,5‐alkyldiynol and 1H,1H‐perfluoro‐2,4‐alkyldiynol is reported. Their solution homopolymerisation was studied in t
