Expanding the use of fluorine in pharmaceuticals, agrochemicals and materials requires a widely applicable and more efficient protocol for the preparation of fluorinated compounds. We have developed a new generation nucleophilic fluorination reagent, KHSO4-13HF, HF 68 wt/wt %, that is not only easily handled and inexpensive but also capable of hydrofluorinating diverse, highly functionalized alkenes, including natural products. The high efficiency observed in this reaction hinges on the activation of HF using a highly "acidic" hydrogen bond acceptor.

, (2015/05/06)
The present invention relates to novel oxodihydropyridinecarbohydrazide derivatives with excellent antifungal activities, an antifungal composition containing the same, and its use for the prevention and treatment of fungal infectious diseases. The oxodihydropyridinecarbohydrazide derivatives of the present invention have excellent antifungal and fungicidal activities, and thus will be useful for the prevention and treatment of various fungal infections by Candida spp., Aspergillus spp., Cryptococcus neoformans and Trichophyton spp., etc. Additionally, the oxodihydropyridinecarbohydrazide derivatives of the present invention, unlike other fungicidal preparations, can be orally administered.

A transition-metal-free method for the synthesis of C6 phenanthridine derivatives by arylative cyclization of 2-isocyanobiphenyls with arylamines in one pot was developed. Mechanistic studies suggest that electrophilic aromatic substitution (SEAr) of a nitrilium intermediate and homolytic aromatic substitution (HAS) of an imidoyl radical intermediate are two competitive reaction pathways involved in the annulation step.
Cyclizing radical carboiodination, carbotelluration, and carboaminoxylation of aryl amines

, p. 8180 - 8183 (2014/08/18)
Radical carboiodination of various aryl amines is reported. Aryl diazonium salts, generated in situ from the corresponding aryl amines, are reacted with Bu4NI to provide the corresponding aryl radicals which undergo 5-exo or 6-exo cyclization. Iodine abstraction eventually affords the carboiodinated products in good to excellent yields. If TEMPO is added, the cascade provides the cyclized carboaminoxylation products. Running the reaction in the presence of PhTeTePh affords the phenyltellurated cyclized products.
Twofold carbon-carbon bond formation by intra- and intermolecular radical reactions of aryl diazonium salts
Jasch, Hannelore,Landais, Yannick,Heinrich, Markus R.
, p. 8411 - 8416 (2013/07/11)
Cascade reactions: A variety of novel cascade reactions can be performed when the known and well-studied radical 5- or 6-exo-cyclization of an aryl diazonium salt is conducted in the presence of alkenes and further optional scavengers (see scheme). Copyri
Design of postmetallocene catalytic systems of arylimine type for olefi n polymerization: XV. Synthesis of (N-Aryl)salicylaldimine ligands containing a but-3-enyloxy group and their complexes with titanium(IV) dichloride

, p. 1150 - 1156 (2013/10/01)
A series of (N-aryl)salicylaldimines was synthesized by the reaction of salicylaldehydes substituted in the positions 3 and 5 by bulky tert-butyl or α-cumyl groups with hydrochlorides of o-, m-, and p-(but-3-enyloxy) aniline in the presence of triethylamine. The obtained compounds formed by the reaction with TiCl2(OPr-i)2 complexes of titanium(IV) dichloride L2TiCl2.
Intramolecular 1,3-Dipolar Cycloaddition Reactions of Alkenyl-substituted 3,4-Diarylsydnones

, p. 927 - 940 (2007/10/02)
The 3,4-diarylsydnones 1 and 12a-e with an allyl or alkenyloxy substituent on the N(3)-phenyl group have been synthesized by classical methods starting from 2-allylaniline and the corresponding alkenyloxyanilines, respectively (Schemes 2 and 3).Whereas th
