Bis(trimethylsilyl)-phosphaethene und Tris(trimethylsilyl)silyl-fluorphosphane

Zeitschrift für Naturforschung B, 1984
Abstract Phosphaethenes of the type (Me3Si)2C = P -NRSiMe3 R = C10H15 (7), CMe3 (8), 2.4.6-Me3C6H2 (10)), LiF, and Me3SiF are obtained in the reaction of the aminodifluorophosphanes (3-5) with the lithium salt of tris(trimethylsilyl)methane (1). 10 is isolated as by-product. The main product is F2PC(SiMe3)3 (9). The lithium salt of tris(

Membrane Polymers for the Pervaporative Separation of Polar Organics: Methanol and Acetonitrile

Journal of Applied Polymer Science, EarlyView.
We tested seven polymers as membranes for the pervaporative separation of methanol‐acetonitrile mixtures. Chloroprene rubber, silicone rubber, and Matrimid showed effective separation by favoring acetonitrile transport, enabling azeotrope breaking. Plasticization was assessed using Broadband Dielectric Spectroscopy.

Chemical Profiling, In Silico and In Vitro Studies to Identify Potential CDK2 and mTOR Inhibitor From Selaginella inaequalifolia (Hook. & Grev.) Spring Ethanolic Extracts

Chemistry &Biodiversity, EarlyView.
ABSTRACT The current study is aimed to reveal the phytoprofile of Selaginella inaequalifolia (Hook. & Grev.) Spring using GC–MS and predict the drug properties, toxicity, biological properties of S. inaequalifolia ethanolic extracts (SiEE) using in silico methods and in vitro toxicity assays, namely, MTT and BSLB assay.
