Abstract:
Splendid isolation: Monomeric phosphazene F(2)PN ((1)A(1)) was prepared for the first time through irradiation of F(2)PN(3) in an argon matrix with an ArF excimer laser (lambda=193 nm). Upon subsequent irradiation with a high-pressure mercury arc lamp (lambda=255 nm), F(2)PN undergoes a 1,2-fluorine shift to give iminophosphane cis-FP=NF.
