Synthesis of amino substituted methanofullerenes in the presence of Ti(Oi-Pr)4

A novel approach for the synthesis of C60 fullerenes containing strained 2,3-dimethylenebicyclo[2,2,0]hexane fragments

A novel approach for introducing strained 2,3-dimethylenebicyclo[2,2,0]hexane structures into the C₆₀ fullerene molecule, based on the reaction of C₆₀ with substituted propargylamines, promoted by the Ti(Oi-Pr)₄ and EtMgBr system.

Synthesis and Electrochemical Properties of Fullerenylstyrenes

An efficient preparative method was developed for the synthesis of previously unreported fullerenylstyrenes based on the reaction of C₆₀ fullerene with terminal acetylenes and EtMgBr in the presence of Ti(Oi-Pr)₄. The voltammetric curves of the prepared fullerenylstyrenes were studied, and good prospects for their application as acceptor materials for bulk heterojunction solar cell were demonstrated.

Nucleophilic cyclopropanation of [60]fullerene by the addition-elimination mechanism

Information on the synthesis of monofunctionalized methanofullerenes C60 obtained by the addition-elimination mechanism is generalized. The main reagents for cyclopropanation, mechanisms and optimal conditions for the processes, and the prospects for practical application of the products are considered.

Aminomethylation of Fullerene C60 with N,N',N″-Triaryl- or N,N',N″-Trihetaryl-1,3,5-perhydrotriazines in the Presence of EtMgBr and Ti(Oi-Pr)4

A new method for the functionalization of fullerenes based on the reaction between in situ generated aryl- or hetaryl-containing 1,3,5-perhydrotriazines and EtMgBr in the presence of Ti(Oi-Pr)₄ has been developed. The cleavage of the triazine ring under previously developed conditions1-6 results in the formation of aminomethylated derivatives of fullerene C₆₀ with high yields (80-90%) and selectivity (∼90%).

New one-pot method for the synthesis of pyrrolidinofullerenes

The reaction of fullerene C₆₀ with isocyanoacetates and EtMgBr in the presence of stoichiometric amounts of Ti(Oi-Pr)₄ was studied for the first time.
