Reaction of freshly prepared C60Cl6 (from chlorination of [60]fullerene by ICl in benzene) with methyllithium followed by hydrolysis and work-up including HPLC separation yields Cs symmetry C60Me6 (isostructural with C60Br6 and C60Cl6), ... Hamad,Al-Matar,Ala'a,... - 《Journal of the ...
Organic ChemistryKinetics and mechanism of micellar catalyzed N-bromosuccinimide oxidation of dextrose in H2SO4 medium was investigated under pseudo-first-order condition temperature of 40??C. The results of the reactions studied over a wide range of experimental conditions show that NBS shows a ...
