Abstract
This article describes the regioselective synthesis of novel nitroso-pyrazolylquinoxalines via cyclocondensation of 2-hydroxyimino-1,3-diketones with hydrazinylquinoxalines. Of note, this is the first time that 2-hydroxyimino-1,3-diketones are used as electrophilic reagents to cyclocondensation with hetarylhydrazines. The cyclocondensation proceeded through a hydrazone intermediates formation. A series of novel nitroso-substituted pyrazolylquinoxalines were synthesized by both "one-pot" and "two-step" procedures in up to 86% yields. Importantly, a gram-scale synthesis of nitroso-pyrazolylquinoxalines, their oxidation and reduction were successfully accomplished.

Abstract
The hetero-Diels-Alder reaction between a nitroso dienophile and a conjugated diene to give the 3,6-dihydro-2H-1,2-oxazine scaffold is useful for the synthesis of many biologically interesting molecules due to the diverse opportunities created by subsequent transformations of the resulting 1,2-oxazine ring. This review discusses the rationale for the observed regio- and stereoselectivity and the methods developed in recent years used to control and improve the stereo- and regioselectivity for the synthesis of 1,2-oxazine scaffolds.

Abstract
The reaction between p-nitrosonitrobenzene and the tetramethylpropylenediamine-copper(i) complex yields a dinuclear complex that is structurally and electronically similar to side-on peroxo species known in Cu/O2 chemistry. The complex reacts with di-tert-butylphenolate via nitrene transfer, as observed through an intermediate and the aminophenol product obtained upon reductive work-up.

Abstract
Oxidative cyclization by reaction of benzylic and phenolic OH groups on tricarbonyl(η(4)-cyclohexa-1,3-diene)iron(0) complexes has been achieved with the hypervalent iodine oxidant PIFA which was shown to be compatible with the tricarbonyliron complex. The reaction proceeds with substrates with the nucleophilic substituent on the opposite face of the ligand to the iron. IBX gives efficient oxidation of the benzyl alcohol to the aldehyde in the presence of the Fe(CO)(3) group. Reduction of 1-arylcyclohexadienyliron(1+) complexes with sodium borohydride to access the endo series also gave a novel rearranged 2-aryl reduction product with a 5-endo OMe group. The cis relative stereochemistry of the oxidative cyclization product, the exo delivery of hydride to the 1-arylcyclohexadienyliron(1+) complex, and the 2-aryl-5-endo-methoxy relative stereochemistry of the rearranged product were proved by X-ray crystallography.

Abstract
Organotrifluoroborates have emerged as an alternative to toxic and air- and moisture-sensitive organometallic species for the synthesis of functionalized aryl and heteroaryl compounds. It has been shown that the trifluoroborate moiety can be easily converted into a variety of different substituents in a late synthetic stage. In this paper, we disclose a mild, selective, and convenient method for the ipso-nitrosation of organotrifluoroborates using nitrosonium tetrafluoroborate (NOBF(4)). Aryl- and heteroaryltrifluoroborates were converted into the corresponding nitroso products in good to excellent yields. This method proved to be tolerant of a broad range of functional groups.
