✦ Synopsis

The complexation of aryldiazonium ions by macrocyclic polyetheIs(crown ethers) has been demonstrated by spectroscopic,1 kinetic,' and calorimetric studies.

3 One to one complexes of aryldiazonium salts and crown ethers have been isolated. 2,4 We now report studies of aryldiazonium ion complexation by acyclic polyethers (glymes).

Considerable attention is currently being focused upon the use of glymes and other oligoethylene glycol ethers, CH O(CH CH 0) CH

Crown ether complexes of aryldiazonium ions exhibit markedly enhanced thermal stability relative to the corresponding uncomplexed salts. ' Thus, the thermal decomposition (Schiemann reaction) of P-tert-butylbenzenediazonium fluoroborate in 1,2-dichloroethane is retarded by the presence of 18-crown-6
