Mono-, di-, and trisubstituted acyl and alkyl thiophenes. I. Synthesis, ultraviolet, and proton magnetic resonance spectra

Abstract

The synthesis of 63 mono-, di-, and trisubstituted acyl and alkyl thiophenes Is reported, and the ultraviolet, infrared, and PMR spectra are discussed.

Mono-, di-, and trisubstituted acyl- and alkylthiophenes. 2. Mass spectrometry

“…2-( 2-Methyl-dz) -decanoyl-4-methyl-5-n-trldecylthlophene. The compound was synthesized from 2-n-decanoyl-4-methyl-5-n-tridecylthiophene and CD3I (99% isotopic purity) in the presence of dimsyl ion by the procedure described earlier for the analogous unlabeled compound (13). The compound was purified for mass spectrometry by GLC. Literature Cited…”
