Synthesis and spectroscopic properties of geminal-bis(tert-butylamino)
cyclotriphosphazenes obtained by the reaction of spiro
and ansa phenoxycyclotriphosphazenes with the tert-butylamine
and the crystal structure of 4,4’-bis(tert-butylamino)-2,6’,6’,10-
-tetrachloro-4’,4’,6’,6’-tetrahydrospyro[12H-dibenzo[d,g]-
[1,3,2]dioxaphosphocin-6,2’?5-[1,3,5,2,4,6]-triazaphosphorine]
