[10] In arecent study, Jones and Frenking argued that phosphinazine (Ph 3 P) 2 N 2 , am olecule that cleanly decomposes into PPh 3 and N 2 when heated above 210 8 8C, is best described as aL ewis acid-base adduct between N 2 in the 1 G g reference state and free PPh 3 . [11] However,i ts direct synthesis from N 2 and PPh 3 was not reported.…”
