Catalytic Three‐Component Ugi Reaction [PDF]
Angewandte Chemie International Edition, 2008 Perfect atom economy characterizes a novel catalytic three‐component Ugi reaction (see example). Different α‐amino amides are formed in good yields from aldehydes, primary amines, and isocyanides in the presence of phenyl phosphinic acid as the catalyst. The products will be useful for the synthesis of α‐amino acid derivatives and in diversity‐oriented

Sufficient conditions for wave instability in three-component reaction-diffusion systems [PDF]
, 2013 Sufficient conditions for the wave instability in general three-component reaction-diffusion systems are derived. These conditions are expressed in terms of the Jacobian matrix of the uniform steady state of the system, and enable us to determine whether

Chemical Association via Exact Thermodynamic Formulations [PDF]
, 1998 It can be fruitful to view two-component physical systems of attractive monomers, A and B, ``chemically'' in terms of a reaction A + B C, where C = AB is an associated pair or complex.

Role of the total isospin 3/2 component in three-nucleon reactions [PDF]
, 2016 We discuss the role of the three-nucleon isospin T=3/2 amplitude in elastic neutron-deuteron scattering and in the deuteron breakup reaction. The contribution of this amplitude originates from charge-independence breaking of the nucleon-nucleon potential

5-(4-Fluorophenyl)-3-(naphthalen-1-yl)-1-phenyl-1H-pyrazole
Molbank, 2021 A new fluorinated pyrazole, 5-(4-fluorophenyl)-3-(naphthalen-1-yl)-1-phenyl-1H-pyrazole was successfully synthesized via a two-step reaction. Firstly, the synthesis of pyrazoline was performed via one-pot three-component reaction under microwave ...

New description of four-body breakup reaction [PDF]
, 2010 We present a novel method of smoothing discrete breakup cross sections calculated by the method of continuum-discretized coupled-channels. The method based on the complex scaling method is tested with success for $^{58}$Ni($d$, $pn$) reaction at 80 MeV ...
