Selective N-prop-2-ynylation of heterocycles induced by solid–liquid phase transfer catalysis without solvent and use of solid inorganic supports
Abstract
Complementary processes promote the N-prop-2-ynylation of heterocycles: solid-liquid phase transfer catalysis without added solvent in the presence or absence of alumina or titanium dioxide and alkylation on ‘basic’ alumina in ‘dry media’.
