Controlled Organocatalytic Ring-Opening Polymerization of ε-Thionocaprolactone.
For the first time, the controlled ring-opening polymerization (ROP) of ε-thionocaprolactone (tnCL) is conducted. The organocatalytic ROP of tnCL occurs without carbonyl scrambling, leading to homopoly(ε-thionocaprolactone) (PtnCL). The ROP by base catalysts alone is proposed to proceed via a nucleophilic mechanism, while the addition of an H-bond donating thiourea (TU) is shown to provide exce...
متن کاملSynthesis of Polyamide 6 by Anionic Polymerization of ε-Caprolactam in an Internal Mixer: Effect of Polymerization Reaction Time
The main objective of the present work was to synthesis polyamide 6 through anionic polymerization of ε-caprolactam in an internal mixer. The reaction time and the rheological properties of samples during the polymerization were studied. The samples were characterized by Thermo Gravimetry Analysis (TGA), Differential Scanning Calorimeter (DSC) and FT-IR spectrometer. The melt flow behavior and ...
متن کاملBeryllium derivatives of a phenyl-substituted β-diketiminate: a well-defined ring opening reaction of tetrahydrofuran.
The phenyl-substituted β-diketiminate ligand precursor (Ph)LH, [(Dipp)NC(Ph)CHC(Ph)NH(Dipp)] (Dipp = 2,6-di-isopropylphenyl) and its lithium and beryllium halide derivatives [(Ph)LLi(OEt2)], [(Ph)LBeCl] and [(Ph)LBeI] have been synthesised and characterised by NMR and X-ray structural analysis. The iodoberyllium complex [(Ph)LBeI] reacts with THF in a well-defined ring-opening insertion reactio...
متن کاملAmino-caprolactam derivatives as gamma-secretase inhibitors.
A series of amino-caprolactam sulfonamides were developed from a screening hit. Compounds with good in vitro and in vivo gamma-secretase activity are reported.
متن کاملDesign, Synthesis and Antifungal Activity of Coumarin Ring-Opening Derivatives.
Based on our initial design, we synthesized two series of coumarin ring-opening derivatives by the reactions of hydrolysis and methylation. Results of antifungal screening in vitro showed that the target compounds exhibited potent activity against the six common pathogenic fungi. Compounds 6b, 6e, 6g, 6i, 7b and 7c were identified as the most active ones, and the EC50 values of these active com...
