Rearrangement of O,O’-bis(2-benzylideneaminophenyl) phenylphosphonite into 1,6,7-triphenyl-3,4:9,10-dibenzo-2,11-dioxa-5,8-diaza-1-phosphatricyclo[6.3.0.01,5]undeca-3,9-diene
摘要:
Keeping of O,O'-bis(2-benzylideneaminophenyl) phenylphosphonite in a CCl4 solution for 50 days resulted in its spontaneous rearrangement into 1,6,7-triphenyl-3,4: 9,10-dibenzo-2,11-dioxa-5,8-diaza-1-phosphatricyclo[6.3.0.0(1,5)]undeca-3,9-diene, a representative of spirophosphoranes with P-N bonds.
