Metal free oxidation of vinamidine derivatives: a simple synthesis of $\alpha$-keto-$\beta$-diimine ligands.

Oxidn. of [3-(dimethylamino)-1,3-diphenylprop-2-en-1-ylidene]dimethylazanium chloride with meta-chloroperbenzoic acid is the key synthetic step towards new persistent 1,3-di(amino)oxyallyl radical cations. When applied to parent vinamidines R1HNC(R)=CHC(R)=NR1 (R = CH3, C6H5, N(CH3)2; R1 = 2,6-bis(propan-2-yl)phenyl, mesityl, C6H5), this protocol allows for a simple straightforward synthesis of $\alpha$-keto-$\beta$-diimine ligands R1N=C(R)C(O)C(R)=NR1, for which no convenient synthesis was previously available.
