ZnCl2-catalyzed synthesis of α-dithiocarbamato-alkyl-β-naphthols via the Betti reaction under solvent-free conditions

The synthesis of α-dithiocarbamato-alkyl-β-naphthols is reported via the Betti reaction of naphthols, aldehydes and ammonia-based dithiocarbamates in the presence of ZnCl2 under solvent-free conditions. High to excellent yields and simple reaction conditions are the main advantages of this reaction.

TRIARYLMETHANE COMPOUNDS

The present invention relates to triarylmethane compounds of the formula (I), which are suitable as monomers for preparing thermoplastic resins having beneficial optical properties and which can be used for producing optical devices. (I) where R1, R2 are e.g. hydrogen; Y is an alkylene group having 2, 3 or 4 carbon atoms, Ar is selected from mono-or polycyclic aryl and mono-or polycyclic hetaryl; X1, X2, X3, X4 are CH, C-Rx or N, provided that in each ring at most two of X1, X2, X3, X4 are N; Rx is e.g. halogen, CN or CH=CH2. The invention also relates to thermoplastic resins comprising a polymerized unit of the compound of formula (I).

Ionic Liquid [DABCO-H][HSO4] as a Highly Efficient and Recyclable Catalyst for Friedel-Crafts Alkylation in the Synthesis of Bis(naphthol)methane and Bis(indolyl)methane Derivatives

A simple and highly efficient approach to the synthesis of bis(naphthol)methane (BNM) and bis(indolyl)methane (BIM) derivatives has been developed. In the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO)-based ionic liquid catalysts, which are environmental friendly, inexpensive, and recyclable, the reaction afforded the corresponding products in good to excellent yields within short times under solvent-free conditions. The catalysts can be easily recovered and reused several times without significant loss in activity.
