Phase transfer catalysis in the chemistry of heterocyclic compounds. A review

This review covers new data on the use of phase transfer catalysis in the chemistry of heterocyclic compounds. The following reactions are considered: alkylation, acylation, reactions with dihalocarbenes, preparations of ethers and esters, the formation of halo derivatives, oxidation and reduction, and isotope exchange. The advantages of phase transfer catalysis are examined and the prospects for its further development in heterocyclic chemistry are discussed.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1443–1459, November, 1983.
