摘要:... These ethoxylates and free alcohol were derivatized for LC–MS/MS analysis with phenyl isocyanate (PIC). The derivatives of analytes with PIC were separated using a C18 column. Gradient elution with a mixture of ethyl acetate and acetonitrile (5 mM) was employed. The desc...

摘要:Abstract(#br)The reactions of carbanions of diethyl phenyl and 4-nitrophenylmalonates with phenyl isocyanate occur with 1,3-C→N migration of the ethoxycarbonyl group to form the corresponding adducts. The introduction of NO 2 groups into the benzene ring of arylmalonates i...

摘要:Abstract(#br)A new reaction of the insertion of phenyl isocyanate into the C-C bond of P-containing zwitterions based on 2-cyanoacrylates was found. A probable mechanism of this reaction has been discussed.

摘要:Abstract(#br)Novel heterocyclic dihydropyrimidine-2,4,5(3H)-triones and tetrahydro-2-thioxopyrimidine-4,5-diones were synthesized via three-component reaction between appropriate amines, phenyl isocyanate or phenyl isothiocyanate, and ethyl bromopyruvate in DMF under reflux condi...

摘要:... We investigated the immunologic activity of phenyl isocyanate (PI), an aromatic monoisocyanate, which is a trace constituent in commercial diphenyl methane diisocyanate (MDI) products, since it is has been reported to cause an ‘asthma-like’ syndrome in rats. The potency ...

摘要:Abstract(#br)A derivatization procedure using phenyl isocyanate was adapted to liquid chromatography ion trap mass spectrometry (LC–MS n ) for confirmation and quantification of aminoglycoside residues in milk. Aminoglycoside residues were extracted from milk with acid and...

摘要:... of phenyl isocyanate at room temperature in diethyl ether results in the PhNCO being inserted seletively into hafnium–NEt 2 bonds to generate [C 4 H 3 N(CH 2 NMe 2 )-2] 2 Hf[PhNC(NEt 2 )O] 2 ( 2 ) in 56% yield. Similarly, while reacting 1 with 2 equiv. of phenyl isocyanate...

摘要:Abstract(#br)Thermal coupling of vinyl aziridines and phenyl isocyanate was evaluated. Although oxazolidinone products were predominant, some reactions afforded a seven-membered ring heterocycle. When Ni/IMes was employed as a catalyst, a wider array of vinyl aziridines underwent...

摘要:Abstract(#br)The synthesis of a novel class of 3‐[bis(dimethylamino)methylidene]‐1,1‐diarylureas via a Cu‐catalyzed multicomponent reaction of phenyl isocyanate (PhNCO), 1,1,3,3‐tetramethylguanidine, and aryl halides is described.
