Microwave-assisted three-component domino reaction: Synthesis of indolodiazepinotriazoles
Beilstein Journal of Organic Chemistry, 2013 A microwave-assisted three-component protocol involving N-1 alkylation of 2-alkynylindoles with epichlorohydrin, ring opening of the epoxide with sodium azide, and an intramolecular Huisgen azide–internal alkyne 1,3-dipolar cycloaddition domino sequence ...

ACS Catalysis, 2019 Acatalytic dearomative three-component reaction of bromoarenes with TMS-diazomethane and allyl borate was developed. The key of this assembling reaction is the use of a diazo compound to generate a Pd-π-benzyl intermediate through a Pd-carbenoid species.

Benzannulated Bicycles by Three‐Component Aryne Reactions
Angewandte Chemie International Edition, 2011 Triple crown: A pair of three-component coupling reactions between arynes, isocyanides, and either activated alkynes or phenyl esters generates unusual iminoindenones or phenoxy iminoisobenzofurans (see scheme), the latter of which may be advanced to o-ketobenzamides by performing direct hydrolysis.

Unfolding symmetric Bogdanov-Takens bifurcations for front dynamics in a reaction-diffusion system [PDF]
, 2019 This manuscript extends the analysis of a much studied singularly perturbed three-component reaction-diffusion system for front dynamics in the regime where the essential spectrum is close to the origin.

A Nanovessel-Catalyzed Three-Component Aza-Darzens Reaction [PDF]
Journal of the American Chemical Society, 2020 It has been previously demonstrated that nanovessels can be highly competent catalysts providing high rate accelerations and unique selectivity to the organic transformations which they mediate. However, for supramolecular assemblies to be considered a standard reagent in organic synthesis they must first demonstrate the ability to catalyze ...

Saturation of front propagation in a reaction-diffusion process describing plasma damage in porous low-k materials [PDF]
, 2011 We propose a three-component reaction-diffusion system yielding an asymptotic logarithmic time-dependence for a moving interface. This is naturally related to a Stefan-problem for which both one-sided Dirichlet-type and von Neumann-type boundary ...

Fast reaction limit of a three-component reaction–diffusion system
Journal of Mathematical Analysis and Applications, 2011 The authors consider a three-component reaction-diffusion system with a reaction rate parameter, and investigate its singular limit as the reaction rate tends to infinity. The limit problem is given by a free boundary problem, which possesses three regions separated by the free boundaries.
