Palladium/Copper Cocatalyzed Coupling Reaction of Aroyl Hydrazides with Indoles

An unprecedented palladium/copper cocatalyzed coupling reaction of indoles with simple aroyl hydrazides has been developed under aerobic conditions. A range of aroyl hydrazides underwent palladium/copper cocatalyzed oxidative arylation with indoles open to air in a 1:1 mixture of dimethyl sulfoxide and nitromethane to give structurally diverse 2-arylindoles or 3-arylindoles in moderate to good yields. The reaction well tolerates a wide variety of functional groups such as alkoxy, halo, ester.

Open-Resonance-Assisted Hydrogen Bonds and Competing Quasiaromaticity

The delocalization of electron density upon tautomerization of a proton across a conjugated bridge can alter the strength of hydrogen bonds. This effect has been dubbed resonance-assisted hydrogen bonding (RAHB) and plays a major role in the energetics of the tautomeric equilibrium. The goal of this work was to investigate the role that pi-delocalization plays in the stability of RAHBs by engaging other isomerization processes. Similarly, acid-base chemistry has received little experimental attention in studies of RAHB, and we address the role that acid-base effects play in the tautomeric equilibrium. We find that pi-delocalization and the disruption of adjacent aromatic rings is the dominant effect in determining the stability of a RAHB.

From bifunctional nucleophilic behavior of DBU to a new heterocyclic fluorescent platform

(Chemical Equation Presented) An unexpected discovery of a novel cyclocondensation reaction of 1,8-diazabicyclo[5.4.0]undec-8-ene (DBU) with activated 1,2-dichloro compounds is described. The 2-aminopyrrole skeleton is generated through the concomitant formation of new nitrogen-carbon and carbon-carbon bonds. A new pentacyclic derivative formed upon the reaction of 2,3-dichloroquinoxaline with DBU exhibits strong fluorescence both in solutions (Phi in hexane = 0.4) and in the solid state.

THE ALKYLATION OF QUINOXALINO<2,3-b><1,4>BENZOTHIAZINES UNDER PHASE-TRANSFER CATALYSIS CONDITIONS

Quinoxalino<2,3-b><1,4>benzothiazine (mainly in the 12H form) has been alkylated using the phase-transfer catalysis technique.Two N-alkylated isomers, 1x and 2x (in 7:3 ratio), are obtained.Similarly, its chloro derivative present in the 12H form as 8-(3a) and 9-chloro (5a) isomers in 1:1 ratio has been alkylated.Each isomer affords the corresponding pair of N-alkylated isomers.In some cases, these isomers or isomer mixtures could be separated by preparative TLC; they have been identified by UV and 1H-NMR spectroscopy and their ratios determined using photodensitometric and fluorimetric methods.

Synthesis of molecular-gripper-type dynamic receptors and STM-imaging of self-assembled monolayers on gold

Dynamic receptors capable of undergoing large temperature or pH-dependent conformational changes were functionalised with dialkyl thioether legs and adsorbed on Au(111) single crystal surfaces to give self-assembled monolayers (SAMs). The SAMs were characterised by ellipsometry and contact angle measurements. Imaging by scanning tunnelling microscopy (STM) revealed well-ordered monolayers at molecular resolution.
