Easy functionalization of carbon nano-onions with disulfides and their use as recyclable heterogeneous organocatalysts

A facile functionalization of carbon nano-onions (CNO), through an atom economical one-step process, with a series of different generation (2.0, 2.5, and 3.0G) poly(amidoamine) (PAMAM) dendrimers with a cystamine core and endowed with either methyl ester or amino groups in the periphery has been rep...
