Chlorination of geminal bis(alkoxy-NNO-azoxy) compounds with sodium hypochlorite
摘要:
Chlorination of geminal bis(alkoxy-NNO-azoxy) compounds with sodium hypochlorite involves the central carbon atom and gives 1,1-bis(alkoxy-NNO-azoxy)-1-chloroalkanes with high yield. Dichlorobis-(methoxy-NNO-azoxy)methane oxidizes sodium iodide to elemental iodine. The signal from the central carbon atom in the C-13 NMR spectra of bis(alkoxy-NNO-azoxy)dichloromethanes is broadened and displaced downfield relative to those of the initial compounds.
Alkylation of 1,1-bis(methoxy-NNO-azoxy)alkanes under phase-transfer catalysis
摘要:
1,1-Bis(methoxy-NNO-azoxy)alkanes were alkylated in high yield at the central carbon atom under conditions of phase-transfer catalysis with selective formation of mono- and dialkyl derivatives.
