SYNTHESES OF ANTIMONY(V) DERIVATIVES FROM TRIMETHYL AND TRIPHENYLANTIMONY(III), DIHYDRIC PHENOLS, AND TERT-BUTYL HYDROPEROXIDE

Trimethyl and triphenylantimony o-phenylene dioxides were obtained by the reaction of trimethyl- and triphenylantimony with pyrocatechol in the presence of tert-butyl hydroperoxide in 68 and 81 % yields, respec tively. 7,7,7,15,15,15-Hexamethyl-(and phenyl)-6,8,14,16-tetraoxa-7, c lo[11.3.1.1(9,13)]octadeca-1,3,5,9,11,13-hexaenes were synthesized ana logously by the reaction with resorcinol (in 79 and 93 % yields, respe ctively). The use of hydroquinone resulted in polymeric trimethyl- and triphenylantimony hydroquinolates.
