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.

PyC60-naphthacrown system: A new supramolecular recognition element

(Graph Presented) Fulleropyrrolidine (PyC60) and a binaphthyl bridged crown ether macrocyclic receptor (1) undergoes spontaneous self-assembly phenomenon in solution to generate a new supramolecular recognition element having binding constant value of ～5.83 × 104 dm3 mol-1. Lifetime measurement reveals a static quenching mechanism behind the deactivation of photoexcited state of 1 in presence of PyC60. The results obtained from this work would definitely reinforce bridged cyclic crown ether as one of the most suitable fragments for the molecular recognition of various macrocyclic receptor(s) in near future.

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).

N,N-disulfo-1,1,3,3-tetramethylguanidinium carboxylate ionic liquids as reusable homogeneous catalysts for multicomponent synthesis of tetrahydrobenzo[a]xanthene and tetrahydrobenzo[a]acridine derivatives

Three new –SO3H functionalized N,N-disulfo-tetramethylguanidinium carboxylate ionic liquids [DSTMG][CX3COO], ( where X?=?H, Cl, F) were prepared as viscous liquids from the reaction of [DSTMG][Cl] with equimolar amount of three carbo

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.

Novel and potent Lewis acid catalyst: Br2-catalyzed Friedel-Crafts reactions of naphthols with aldehydes

A discovery that the inexpensive Br2 can serve as a potent Lewis acid catalyst for bis(2-hydroxy-1-naphthyl)methanes synthesis is presented. Under the catalysis of Br2 at room temperature, naphthols reacted smoothly with various aldehydes with high efficiency and broad substrate scope. This reaction used to require highly acidic conditions and/or high temperature and/or pressure, and sometimes featured poor yields. Moreover, theoretical calculations suggested that Br2 is a potent Lewis acid to activate the carbonyl group, yet it was not the primary cause for the remarkable activity of Br2 in the current communication.

Recognition of steric factor in external association of xanthenocrown-5 and bis-napthalenocrown-6 with bis(benzimidazolium)propane borontetrafluoride

This is the first report of charge transfer band for crown-axel H-bonding interaction in acetonitrile medium. Monte Carlo simulation established external association of small cavity crown with BBIM-propane dication axels. Resonance energy, binding constant and ratiometric detection of association of xanthenocrown-5 (1) and bis-napthalenocrown-6 (2) with bis-(benzimidazolium)propane borontetrafluoride (3a-3d) in acetonitrile determined the effect of steric factor towards association.

Synthesis of anti-2,3-dihydro-1,2,3-trisubstituted-1H-naphth [1,2-e][1,3]oxazine derivatives via multicomponent approach

A series of anti-2,3-dihydro-1,2,3-trisubstituted-1H-naphth [1,2-e][1,3]oxazine derivatives 6 were exclusively obtained in high yields for the first time through multicomponent reactions (MCRs) of 2-naphthol, aromatic aldehydes and electron rich primary amines in ethanol at room temperature using CCl3COOH as catalyst. The same reaction could be conducted effectively in solvent-free medium at 100 °C. The stereochemistry of the two hydrogens connected to C-2 and C-4 (1,3) positions of the oxazine ring are identified as anti-orientation by single crystal XRD, COSY and NOESY analysis.

Investigation of keto-enol tautomers during the synthesis of aryl-bis (2-hydroxy-1-naphthyl)methanes

This study investigated the existence of keto-enol tautomers for the first time during the synthesis of aryl-bis(2-hydroxy-1-naphthyl)methane from 2-naphthol and p-tolualdehyde or 4-chlorobenzaldehyde in methanol using CuSO4.5H2O as catalyst under reflux condition. The exclusive formation of aryl-bis(2-hydroxy-1-naphthyl)methanes was observed in dichloromethane at room temperature in the presence of BF3.OEt2/AcOH as catalyst. The keto products were isolated and characterized by 1H NMR, 13C NMR, COSY and DEPT spectra. [Figure not available: see fulltext.]

Hydrobromic acid-catalyzed Friedel-Crafts type reactions of naphthols

Catalyzed by 10 mol% of hydrobromic acid, hydroxyalkylation and allylation-iodocyclization of naphthols proceeded smoothly under mild conditions. In contrast, other Bronsted acids tested, including HCl, HI, HBF4, HPF6, TFA, PTSA, H2SO4, TfOH etc., are almost ineffective under identical conditions or require harsh reaction conditions.
