New representatives of phosphorylated methanofullerenes were prepared by the reactions of [60]fullerene with O,O-diethyl α-diazoethyl- and O,O-diethyl α-diazobenzylphosphonates. Electrochemical reduction of the above-mentioned products proceeded stepwise

The simple synthetic procedure for preparation of α-aryl-α-diazophosphonates via a diazo transfer reaction is proposed. Benzylphosphonates reacted with tosyl azide (TsN3) in the presence of potassium tert-butoxide (KOtBu) to afford diazophosphonates in a yield up to 79%. The proposed method is general. The reaction uses easily available starting materials, tolerates various functional groups, and may be applied for multi-gram scale synthesis.
Synthesis of α-aryl-diazophosphonates via palladium-catalyzed cross-coupling of aryl iodides with diethyl diazomethylphosphonate

An efficient procedure for the Pd-catalyzed arylation of diethyl α-diazomethylphosphonate with aryl iodides is described. It can serve as a pathway for the generation of arylated diazophosphonates, which are typically difficult to access. The significance of this methodology was demonstrated via further synthetic transformations of newly synthesized diazo compounds in cyclopropanation, epoxidation, N-H and O-H insertion reactions.
