Abstract A copper‐catalyzed cascade cyclization of 1,6‐enynes with sulfonyl hydrazides for producing various sulfonyl‐substituted γ ‐lactams is described. This radical‐enabled reaction features excellent regioselectivity, mild conditions and broad substrate scope, enabling the formation new C−S C−C bonds through radical sulfonylation, intramolecular hydrogen abstraction. Moreover, relevant experiments have been carried out to probe a possible mechanism.
The preparation of vanadium by molten‐salt electrolysis a commercial carbide (VC) containing 84% was investigated. An electrolytic process developed for the extraction from electrolyte contained in helium‐atmosphere cell at 650°C. effects composition, depletion VC, and cathode current densities on process, as well quality products, were determined. Vanadium 99% purity prepared with an 85% recovery efficiency 70%. approximately 0.60% oxygen had 100 Rockwell B hardness. High‐purity, ductile VC...

The novel polychloromethylation/acyloxylation of 1,6-enynes with chloroalkanes and diacyl peroxides through dual-role designs has been developed to prepare 2-pyrrolidinone derivatives polychloromethyl units the use an inexpensive copper salt under mild conditions. This strategy includes two designs, not only improving atomic utilization but also allowing a cleaner process. wide substrate scope simple reaction conditions demonstrate practicability this protocol.
Abstract Herein we report a protocol for commercial available oxone‐mediated nitration cyclization between 1,6‐enynes and Cu(NO 3 ) 2 . This strategy shows attractive characteristics such as mild reaction conditions, operational simplicity, broad substrates scope with good to excellent yields high functional group tolerance. The provides regioselective way toward the formation of new C−N C−C bonds in one step. Mechanistic studies reveal that procedure undergoes radical process.
In the title Schiff base, C(15)H(13)Br(2)NO, benzene and phenyl rings form a dihedral angle of 75.18 (13)°. The N=C bond length 1.263 (6) Å is shorter than N-C [1.476 (5) Å], indicating double bond. crystal, there some pseudosymmetry. This occurs because most two mol-ecules are centrosymmetrically related. mol-ecular structure stabilized by intra-molecular O-H⋯N hydrogen bonds.
A cyclization/hydrolysis of 1,5-enenitriles for the synthesis valuable pyrrolidine-2,4-diones in aqueous phase using I 2 as catalyst and tert -butyl hydroperoxide (TBHP) oxidant is reported.
In the title Schiff base, C(15)H(14)FN, N=C bond length of 1.263 (2) Å is shorter than N-C [1.426 Å], indicating a typical imine double bond. Moreover, C-N-C angle 118.5 (2)°. The benzene rings form dihedral 51.22 (5)°.
