摘要：

The analysis of dependence of fluorine replacement orientation in 2,4-difluoronitrobenzene effected by nucleophiles Y-C6H4OM (Y = p-OMe, p-Me, m-Me, H, p-F, p-Cl, m-F, m-Cl; M = Li, Na, K, Et4N, Bu4N) in liquid ammonia medium at -35 degreesC on the nature of M, Y, on nucleophile concentration, on addition of crown ethers, diaminoalkanes, and dimethoxyethane indicates the occurrence of ionic association at M = K, Na.
