Chlorination of (Phebox)Ir(mesityl)(OAc) by Thionyl Chloride.

چکیده
Pincer (Phebox)Ir(mesityl)(OAc) (2) (Phebox = 3,5-dimethylphenyl-2,6-bis(oxazolinyl)) complex, formed by benzylic C-H activation of mesitylene (1,3,5-trimethylbenzene) using (Phebox)Ir(OAc)2OH2 (1), was treated with thionyl chloride to rapidly form 1-(chloromethyl)-3,5-dimethylbenzene in 50% yield at 23 °C. A green species was obtained at the end of reaction, which decomposed during flash column chromatography to form (Phebox)IrCl2OH2 in 87% yield.

Activation and Oxidation of Mesitylene C−H Bonds by (Phebox)Iridium(III) Complexes
A pincer iridium(III) complex, (Phebox)Ir(OAc)2OH2 (1) (Phebox = 3,5-dimethylphenyl-2,6-bis(oxazolinyl)), selectively cleaves the benzylic C−H bond of mesitylene to form an isolable iridium mesityl complex, (Phebox)Ir(mesityl)(OAc) (3), in >90% yield. The trifluoroacetate analogue, (Phebox)Ir(OCOCF3)2OH2 (2), was synthesized to compare with complex 1 for C−H activation, and (Phebox)Ir(mesityl)(...
متن کاملNucleosides XII.1 Synthesis of 5Modified Isoguanosines and Reinvestigation of 5DeoxyN3,5cycloisoguanosine
Isoguanosine (3) underwent a coupling reaction with diaryl disulfides in the presence of tri-n-butylphosphine when its 6-amino group was protected by N,N-dimethylaminomethylidene. The synthesis of 5 -deoxyN,5 -cycloisoguanosine (6) and its 2 ,3 -O-isopropylidene derivative (11) were accomplished in excellent yields from isoguanosines (3 & 10) in the presence of triphenylphospine and carbon tetr...
متن کاملChiral multidentate oxazoline ligands based on cyclophosphazene cores: synthesis, characterization and complexation studies.
Chiral oxazoline based bi and hexadentate ligands built on cyclophosphazene cores have been synthesized and characterized. (NPPh2)2[NP(m-OC6H4C(O)OCH3)2] (1) was prepared by the reaction of gem-(NPPh2)2(NPCl2) with methyl-3-hydroxy benzoate in the presence of Cs2CO3. Compound 1 was converted to the dicarboxylic acid (NPPh2)2[NP(m-OC6H4C(O)OH)2] (2) by base promoted hydrolysis with KO(t-Bu). The...
متن کاملOn the reaction of anthranilic acid with thionyl chloride : Iminoketene intermediate formation
It has been reported that sulfinamide anhydride is formed when anthranilic acid is treated with thionyl chloride under anhydrous conditions. Garin et al. reported that no sulfinamide anhydride was formed in the reaction of anthranilic acid with thionyl chloride. They reported that 2-(sulfinylamino) benzoyl chloride was formed, in accordance with an earlier observation, under the same reaction c...
متن کاملA Facile, Improved Synthesis of Sildenafil and Its Analogues
This paper describes the facile synthesis of sildenafil citrate (1) and its related compounds through an improved chlorosulfonation reaction using chlorosulfonic acid and thionyl chloride. This synthesis results in pure sildenafil with high yield. The structures of the compounds were determined with infrared (IR), ¹H-NMR and 13C-NMR spectroscopic methods, and high resolution mass spectroscopy (...
