An efficient method for the preparation of indolin-3-one derivatives from 2-alkynylnitrobenzenes and indoles under alkaline conditions is described. In this reaction, the Wittig process is initiated by PPh3, and then the indole is activated under the action of the base to offer the indolin-3-one substituted by C(2)-indole in up to 98% yield. A variety of functionalized indolin-3-one derivatives were synthesized by modification of 2-alkynylnitroarenes under transition-metal free conditions.

Key words: PPh3, Wittig reaction, 2-alkynylnitroarene, indolin-3-one
