A début for base stabilized monoalkylsilylenes.

An access to base-stabilized three-membered silicon heterocycles.

The three-membered silacyclic ring compounds LSi[N(2)(Ph)(2)]tBu (1), LSi[HCN(Ph)(2)]tBu (2) and LSi[C(2)(Ph)(2)]tBu (3) were obtained by the treatment of base stabilized monoalkylsilylenes LSitBu (L = PhC(NtBu)(2)) with PhN=NPh, PhN=CHPh and PhC≡CPh. The reaction of PhN=NPh and PhC≡CPh with LSitBu shows a different reactivity pattern with base stabilized monochlorosilylene LSiCl. The arrangeme...

Synthesis, Characterization and Catalytic Activity of Ligand Stabilized Palladium Nanoparticle: A Catalyst Compliment to the Heck Coupling Reaction

The palladium metal is the most frequently used metal because of its excellent catalytic efficiency and most flexible varying oxidation state. So,  we report  that palladium nanoparticles (Pd NPs) stabilized by a ligand (o-vanilindiphenylethanedionedihydrazone, L)  using reverse micelles method have been synthesized, while all particles are in spherical shape and ranging between 10 and...

Extraction bayésienne et intégration de patterns représentés suivant les K plus proches voisins pour le go 19x19

Résumé. Cet article décrit la génération automatique et l’utilisation d’une base de patterns pour le go 19x19. La représentation utilisée est celle des K plus proches voisins. Les patterns sont engendrés en parcourant des parties de professionnels. Les probabilités d’appariement et de jeu des patterns sont également estimées à ce moment là. La base créée est intégrée dans un programme existant,...

Mixed Cream Stabilized with Xanthan Gum, a New Substitute for Dairy Cream

A Base-stabilized Iodoborylene Complex of Platinum(II)

The first base-stabilized iodoborylene platinum complex was prepared through the addition of 4-picoline (4-Pic) to a suspension of an iodo-bridged binuclear iodoboryl complex. An X-ray structure determination of the title compound has characterized the molecular structure as cis-[Pt{BI(4Pic)}I2(PCy3)]. The bond lengths lie in the expected range for neutral, base-stabilized borylene complexes. T...
