摘要:
AbstractA series of dialkyl α‐diazophosphonates has been prepared from natural amino acids. The diazo decomposition of these diazophosphonate compounds with tetrakis(acetonitrile)copper(I) hexafluorophosphate/iodine, [Cu(MeCN)4]PF6/I2, as catalyst has been investigated. It was found that the diazo decomposition of dialkyl α‐diazophosphonates gave a mixture of β,γ‐dihydrogen shift and 1,2‐hydride migration products and afforded β‐alkenyl‐substituted β‐amino phosphonates with the Z configuration. The mechanism of this novel diazo decomposition process was discussed.magnified image
