The title complex, [AgBr(C7H7NS)(C18H15P)2], was obtained from the reaction of silver(I) bromide with benzene-carbo-thio-amide (C7H7NS) and tri-phenyl-phosphane (C18H15P) in the mixed solvent of aceto-nitrile and ethanol. The mononuclear complex exhibits a distorted tetra-hedral coordination geometry about the metal atom, arising from one S atom of a benzene-carbo-thio-amide ligand, two P atoms...

Presento el registro fotográfico y comportamiento de un cormorán oliváceo (Phalacrocorax brasilianus) al momento alimentarse pez diablo (Pterygoplichthys sp.) en Villahermosa, Tabasco, México. Esta observación representa primer depredación para los peces México por ave residente, lo que sugiere una presencia abundante la región.

Various isomers of carbo-[3]oxocarbon C9O3 have been characterized on the singlet and triplet spin state potential energy surfaces. Despite its localized structure, the ring carbo-mer of [3]oxocarbon is thermodynamically protected from subsequent isomerization and stable versus dissociation into C3O. It therefore appears as a reasonable synthetic target. In contrast, the less stable tetracyclic...

The title compound, C25H25N3O, comprises a 2-amino-pyridine ring fused with a cyclo-heptane ring, which adopts a chair conformation. The central pyridine ring (r.m.s. deviation = 0.013 Å) carries three substituents, viz. a benzyl-amino group, a meth-oxy-phenyl ring and a carbo-nitrile group. The N atom of the carbo-nitrile group is significantly displaced [by 0.2247 (1) Å] from the plane of the...

Reaction of a variety of dienynes with bis(pinacolato)diboron catalysed by Pd bis(trifluoroacetate) affords allylic boronates containing five or six membered carbo- or heterocycles, by concomitant formation of one C-C and one C-B bonds. Resulting allylboronates can be employed for a variety of subsequent transformations.

Many real-world design problems involve optimization of expensive black-box functions. Bayesian (BO) is a promising approach for solving such challenging using probabilistic surrogate models to systematically tradeoff between exploitation and exploration the space. Although BO often applied unconstrained problems, it has recently been extended constrained setting. Current methods, however, cann...
