A conjugate of fullerene C-60 with methyl 3-oxo-3-(2,4,6-trimethoxyphenyl)propanoate (monoacylation product of 1,3,5-trimethoxybenzene with methyl 3-chloro-3-oxopropanoate) has been synthesized under the Bingel-Hirsch conditions. Redox properties of the conjugate have been studied by cyclic voltammetry.
Operationally Simple and Selective One-Pot Synthesis of Hydroxyphenones: A Facile Access to SNARF Dyes
observed during a Friedel–Craftsacylation/demethylation cascade. In contrast to this cascade, oxygen-containing acylating reagents do not undergo the demethylation step. By the methodology elaborated here, an access is provided to important intermediates for the total synthesis of seminaphthorhodafluor (SNARF) dyes. High selectivity is observed during a Friedel–Craftsacylation/demethylation cascade
