A one-pot method for the synthesis of aromatic ethers using hypervalent iodine(III) reagents obtained from the corresponding iodoaryl compounds is developed. In this concise method, six diaryl ethers and three heterocyclic aromatic ethers are synthesized in good yields. Furthermore, possible mechanisms for the syntheses of the hypervalent iodine reagents and construction of the aromatic ethers are proposed.

Organic nonlinear optical molecular materials have a number of important applications in frequency transformation, electrooptic modulation, two-photon absorption and so on. In this paper, we introduce the main applications of molecular dynamics simulation in theoretical study on nonlinear optical properties of organic molecules, including the electric field poling effects, the local field factors, the nonlinear susceptibilities, and the two-photon absorption. In addition, the important roles played by molecular dynamics simulation in the study of solvent and aggregation effects are also illustrated in combination with the recent research.
