A Simple Method to Evaluate, Correlate and Predict Boiling and Flash Points of Alkynes
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
Boiling points (T-B) of acyclic alkynes are predicted from their boiling point numbers (Y-BP) with the relationship T-B(K) = -16.802Y(BP)(2/3) + 337.377Y(BP)(1/3) - 437.883. In turn, Y-BP values are calculated from structure ...

(Sociedade Brasileira de Química, 2012)
Boiling points (T B) of acyclic alkynes are predicted from their boiling point numbers (Y BP) with the relationship T B(K) = -16.802Y BP2/3 + 337.377Y BP1/3 - 437.883. In turn, Y BP values are calculated from structure ...
Solvent-Reversible Addition of Alkyne C-H Bonds to Water-Soluble NHC Platinum(0) Complexes
(American Chemical Society, 2017-06)
Oxidative addition of CH3I and alkynes to the platinum(0) complex [Pt(AE)NHC] (1), in which the NHC ligand is a sulfonated version of the IPr ligand (1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) and AE is diallyl ...
Base-Free Direct Synthesis of Alkynylphosphonates from Alkynes and H-Phosphonates Catalyzed by Cu2O
(American Chemical Society, 2016-03-04)
A simple and mild methodology for the direct synthesis of alkynylphosphonates is presented. The reaction of a variety of terminal alkynes with dialkyl phosphites in the presence Cu2O (14 mol %) led to the formation of the ...
Selective Semi-Hydrogenation of Terminal Alkynes Promoted by Bimetallic Cu-Pd Nanoparticles
(Georg Thieme Verlag Kg, 2018-11)
The selective semi-hydrogenation of terminal alkynes was efficiently performed, under mild reaction conditions (H 2 balloon, 110 °C), promoted by a bimetallic nanocatalyst composed of copper and palladium nanoparticles ...
Direct synthesis of b -ketophosphonates and vinylphosphonates from alkenes or alkynes catalyzed by CuNPs/ZnO
(Royal Society of Chemistry, 2015-07)
Copper nanoparticles (CuNPs) supported on ZnO have been shown to e ff ectively catalyze the direct synthesis of b -ketophosphonates from alkenes or alkynes, and that of vinyl phosphonates from alkynes and diethylphosphite, ...
Cu2O spheres as an efficient source of catalytic Cu(I) species for performing azide-alkyne click reactions
(Tetrahedron Letters, 2018)
Catalyst- and solvent-free hydrophosphination and multicomponent hydrothiophosphination of alkenes and alkynes
(Royal Society of Chemistry, 2016-05-26)
The hydrophosphination of carbon-carbon multiple bonds has been generally performed under acid, base or metal catalysis in different solvents. Herein, alkyl and alkenyl tertiary phosphines are obtained by the addition of ...
A structure/catalytic activity study of gold(I)-NHC complexes, as well as their recyclability and reusability, in the hydration of alkynes in aqueous medium
(Royal Society of Chemistry, 2016-02)
We conducted a structure/catalytic activity study of water-soluble gold(i) complexes-supporting sulfonated NHC ligands-in the hydration of alkynes in pure water or water nsp;:nsp;methanol (1nsp;:nsp;1), as well as their ...
