A benchtop stable, bifunctional reagent for the redox-neutral cyclopropanation of olefins has been developed. Triethylammonium bis(catecholato)iodomethylsilicate can be readily prepared on multigram scale. Using this reagent in combination with an organic photocatalyst and visible light, cyclopropanation of an array of olefins, including trifluoromethyl- and pinacolatoboryl-substituted alkenes, can

The copper-catalyzed selective mono-N-alkylation of primary amides with bis(trialkylsilyl) peroxides as alkylating agents was reported. The results of a mechanistic study suggest that this reaction should proceed via a free radical process that includes the generation of alkyl radicals from bis(trialkylsilyl) peroxides.

Compounds of formula (Ι') that are Fibroblast Growth Factor Inhibitors (FGFR) and are therefore useful for the treatment of diseases treatable by inhibition of FGFR are disclosed. Also disclosed are pharmaceutical compositions containing such compounds and processes for preparing such compounds.
The present invention relates to a process for preparing N-(1-alkenyl)carboxamides of the formula I, which comprises reacting a carboxamide of the formula II with an alkyne of the formula III in the presence of a catalyst selected from among carbonyl complexes, halides and oxides of rhenium, manganese, tungsten, molybdenum, chromium and iron.
