Definitions
- the present invention relates to the synthesis of new iron-based compounds, their preparation processes and their use as catalysts.
- Iron is a cheap, abundant, easily available and low-toxic metal (Angew. Chem. Int. Ed. 2016, 55, 12150) and tends to replace palladium in the chemical industries. Indeed, iron offers many advantages from a sustainable development point of view. Additionally, iron is one of the few base metals that has been successfully tested as a catalyst in industrial cross-coupling processes on the kilogram scale. Iron ⁇ -dicetiminate complexes have already been used to catalyze hydroamination reactions (Chem. Eur. J. 2019, 25, 835-844). The use of such iron complexes requires working in a controlled atmosphere, in the absence of humidity and ambient air, in “glove box” type equipment. (Chem. Eur. J. 2019, 25, 835-844), which represents a constraint which makes these catalysts difficult to use on an industrial scale.
- metal catalysis is a means of accelerating, or even making possible certain reactions and of accessing a large number of compounds at production costs much lower than conventional organic synthesis routes, these sometimes requiring a number important steps.
- requirements for residual metals in products intended for humans, particularly in products for pharmaceutical use currently represent an obstacle to the use of metal catalysis in the manufacture of such products.
- the Suzuki-Miyaura coupling is used in nearly 25% of drug syntheses based on small molecules and represents 40% of carbon-carbon bond formation reactions while other cross-coupling reactions account for less than 5%.
- this coupling is mainly limited to couplings between 2 partners carrying an sp 2 (or even sp) hybridized carbon leading to the formation of molecules with planar geometry.
- the ease of elimination of Pd(II)-alkyl intermediates formed during the coupling reaction prevents its widespread extension to coupling partners bearing sp 3 hybridized carbons.
- the ligands used to stabilize these catalysts commonly used in industry are phosphorus-based ligands. Since nitrogen is more abundant than phosphorus, chemists are turning to the design of nitrogen-based ligands because it is an advantage from a sustainable development point of view.
- iron-based catalysts for Suzuki-Miyaura coupling have been described in the state of the art, few have been reported to be effective for the coupling of partners bearing sp 3 hybridized carbons.
- coupling with halides tertiary The latter are generally halides that are difficult to couple because of their steric hindrance.
- the object of the invention is to remedy the problem mentioned above and to allow the creation of C(sp 3 )-C(sp 2 ) and C(sp 3 )-C(sp 3 ) bonds.
- An object of the present invention relates to new iron iminoanilide compounds
