Simplified methods for the functionalisation of 3-hexoxythiophenes at the 5-position and further reactions to alkynyl and vinyl derivatives.
Kinetically controlled lithiation of 3-hexoxythiophene in the 5-position allows the synthesis of interesting functionalised building blocks after reaction with N,N-dimethylformamide and iodine.
