“…9-16 Thus, recently synthesized 1,1 bis(methoxy NNO azoxy)ethene (1) 16 turned out to be useful for the introduction of the 2,2 bis(methoxy NNO azoxy)ethyl group into various compounds by the Michael reaction. [16][17][18][19] The key intermediate for the synthesis of 1,1 bis (methoxy NNO azoxy)ethene (1) is 2,2 bis(methoxy NNO azoxy)ethanol (2), 16 which is widely used in the other transformations. 16,18,[20][21][22] Alcohol 2 could be prepared 16,20 by oxymethylation of bis(methoxy NNO azoxy)methane (3) (Scheme 1).…”
