Iodoarenediazonium salts: A new class of aromatic substrates for differential palladium catalyzed reactions

Abstract By virtue of the superior reactivity of diazonium groups over the iodides in Pd-catalyzed rteactions,iodoarenediazonium salts have been investigated and established as a new class of substrates for differential Heck and cross coupling reactions.

Probing the effect of gegenions in Heck reactions of arenediazonium salts: Arenediazonium perchlorates and fluorides as new Heck-substrates

Abstract A study on the gegenion effect in Heck reaction of arenediazonium salts has given rise to arenediazonium perchlorates and fluorides as alternate Heck-substrates to the tetrafluoroborate salts.

A tetraphenylmethane based starburst triarylamine cluster: spectroscopy, electrochemistry and morphological studies

While tetraphenylmethane and triphenylamine are crystalline molecules, a starburst hybrid of the two leads to a low band-gap molecular glass which retains the optical and electrochemical properties of the individual components.

Synthetic studies on tetraphenylmethane dendrimers

Abstract A convergent synthesis of a first generation centrally tetrahedral phenyl cinnamate dendrimer and related dendrons using a multifold Heck reaction strategy is described.

Synthesis of dendritic stilbenoid compounds: Heck reactions for the periphery and the core

A convergent synthetic strategy for stilbenoid dendrimers is described in which multifold Heck reactions have been used to construct both the peripheral and the core stilbene units. Solution optical properties of one of the dendrimers indicated some energy transfer having taken place from the periphery to the core.

FOURFOLD HECK REACTIONS ON THE TETRAPHENYLMETHANE TRIPOD : MODEL STUDIES TOWARDS CONSTRUCTION OF CENTRALLY BASED THREE DIMENSIONAL NETWORKS

Abstract Fourfold Heck reaction on tetraphenylmethane provides a promising ‘one-step’ synthetic methodology for construction of centrally based three dimensional aromatic networks.

Tetraphenylmethane-based tectons in dendrimer synthesis: convergent assembly of ferrocene dendrimers

Abstract A ferrocene dendrimer having nine electrochemically equivalent surface ferrocene units was constructed from a new tetraphenylmethane-based triferrocenyl dendron via a facile convergent approach.

Synthetic studies on dendritic glycoclusters: a convergent palladium-catalyzed strategy

A facile Pd-catalyzed strategy by which multiantennary glycoclusters and sugar dendrons can be readily assembled in one-step is described.

Trivinylogs of Crystal Violet: synthesis and absorption properties of new near-IR dyes

Based on a Heck reaction protocol, trivinylogs of Crystal Violet have been prepared and show strong absorptions in the near-infrared region.

Heck reaction of bis-arenediazonium salts with vinyltriethoxysilane: a new synthetic protocol for poly(1,4-arylenevinylene)s†

A new synthetic protocol for poly(1,4-arylenevinylene)s via the first-ever poly-Heck reaction of arenediazonium salts with vinyltriethoxysilane is described.
