Silver(I)-catalyzed sequential hydroamination and Prins type cyclization for the synthesis of fused benzo--sultams

03-Jul-2018 | B. Maheshwar Rao; J. S. Yadav; B. Sridhar; B. V. Subba Reddy, Organic & Biomolecular Chemistry, 2018

An intramolecular annulation strategy has been developed for the synthesis of tetrahydrobenzo[e]pyrano[4,3-c][1,2]thiazine derivatives by means of coupling of aldehydes with 2-(4-hydroxybut-1-yn-1-yl)-N-arylsulfonamides using a catalytic amount of silver hexafluoroantimonate in toluene at 80 °C. ...

Rare-earth metal bis(aminobenzyl) complexes supported by pyrrolyl-functionalized arylamide ligands: synthesis, characterization and styrene polymerization performance

03-Jul-2018 | Min Li; Chaopan Wang; Hongzhen Xie; Zehuai Mou; Yunjie Luo, Dalton Transactions, 2018

Acid-base reaction between the rare-earth tris(o-dimethylaminobenzyl) complexes Ln(CH2C6H4NMe2-o)3 and the pyrrolyl-functionalized arylamide ligands 2,5-Me2C4H2NCH2SiMe2NHC6H4R (R = H, (HL1); R = Cl-p, (HL2)) was investigated. Treatment of HL1 and HL2 with 1 equiv. of Ln(CH2C6H4NMe2-o)3 in ...

p-TsOH Promoted Synthesis of Benzo-Fused O-Heterocycles from Alkynols via Ring Contraction and C-O Scission Strategy

26-Jun-2018 | Gopal Chandru Senadi; Jeh-Jeng Wang, Green Chemistry, 2018

We here report the first divergent synthesis of benzo-fused O-heterocycles by p-toluene sulfonic acid promoted cascade reactions involving alkyne hydration, double cyclization, ring contraction and C-O bond cleavage from alkynols. Reaction mechanism was validated by obtaining the x-ray structure ...

Self-assembly and friction of glycerol monooleate and its hydrolysis products in bulk and confined non-aqueous solvents

26-Jun-2018 | Joshua L. Bradley-Shaw; Philip J. Camp; Peter J. Dowding; Ken Lewtas, Physical Chemistry Chemical Physics, 2018

Atomistic molecular dynamics simulations are used to study the self-assembly and friction of glycerol monooleate mixed with oleic acid, glycerol, calcium oleate, or water in n-heptane and toluene solvents. The aim is to determine how chemical degradation products of glycerol monooleate could lead ...

Monomeric Fe(III) half-sandwich complexes [Cp[prime or minute]FeX2] - synthesis, properties and electronic structure

26-Jun-2018 | Matthias Reiners; Miyuki Maekawa; Dirk Baabe; Marc-Kevin Zaretzke; Peter Schweyen; Constantin G. Daniliuc; Matthias ..., Dalton Transactions, 2018

The half-sandwich complex [Cp′Fe(μ-I)]2 (1; Cp′ = η5-1,2,4-(Me3C)3C5H2) is cleaved when heated in toluene to form a cation–anion pair [{Cp′Fe(η6-toluene)}+{Cp′FeI2}−] (2), in which the two Fe(ii) atoms adopt different spin states, i.e., a low-spin (S = 0) and a high-spin (S = 2) configuration. ...

Compositional ripening of particle-stabilized drops in a three-liquid system

30-May-2018 | Javier Otero; Steven Meeker; Paul S. Clegg, Soft Matter, 2018

We present experimental studies of two aqueous drops, stabilized by colloidal silica, which are placed close to each other in a bath of toluene, ethanol and surplus colloidal silica. If one of the drops is enriched in ethanol while the other is pure water then we observe the spontaneous formation ...

Some boron compounds of semicarbazones: Antimicrobial activity and precursor for the sol-gel transformation to nanosized boron oxide

29-May-2018 | Jyoti Bhomia; Jyoti Sharma; Ramavtar Sharma; Yash Pal Singh, New Journal of Chemistry, 2018

Some new boron derivatives of the type [(4-C6H4R)C(CH3)NN:C(NH2)OB(OC6H4O)] were synthesized by the reaction of OC6H4OBOPri and LH [LH = (OH)C(NH2)NN:C(CH3)(4-C6H4R)], [where R= H (L1H); CH3(L2H); OCH3(L3H); Cl (L4H); Br (L5H)] in 1:1 molar ratio in refluxing toluene. All these newly synthesized ...

Examination of inequivalent wetting on the crystal habit surfaces of RS-ibuprofen using grid-based molecular modelling

27-May-2018 | I. Rosbottom; J. H. Pickering; B. Etbon; R. B. Hammond; K. J. Roberts, Physical Chemistry Chemical Physics, 2018

Synthonic engineering tools, including grid-based searching molecular modelling, are applied to investigate the wetting interactions of the solute and four crystallisation solvents (ethanol, ethyl acetate, acetonitrile and toluene) with the {100}, {001} and {011} forms of RS-ibuprofen. The ...
