title = "The basic hydrolysis of hexakis(aryloxy)cyclotriphosphazenes",
abstract = "Kinetic and product analysis studies of the alkaline hydrolysis of hexakis(aryloxy)cyclotriphosphazenes in 25 vol.% aqueous diglyme revealed an SN2-type mechanism for cleavage of the first aryloxy-side-group from phosphorus: the hydrolysis rate was considerably enhanced by 2- or 4-nitro-groups and retarded by 4-methyl groups in the aryl ring.",

note = "Funding Information: It is also interesting to note the analogy between the results described here and those reported by Sowerby2 for the SN~exchange of chlorine in hexachlorocyclotriphosphazene. Attempts to follow accurately the cleavage of an additional aryloxy-group from (11) have so far proved unsuccessful, principally because of the slowness of this second step. For example, cleavage of the first aryloxy- group from hexakis- (4-nitrophenoxy) cyclotriphosphazene is 100% complete in 25min at 80{"} with 1 x 10-2N-sodium hydroxide, but removal of a second ligand was not observed during 48 hr of additional treatment.
