Two novel 2-oxybenzothiazole-substituted spiro-2,2 '-dioxybiphenyl cyclotriphosphazene derivatives (3a and 3b) were obtained from these reactions. Both compounds (3a, 3b) have been characterized by elemental analysis as well as by H-1, C-13 and P-31 NMR spectroscopy. Compounds 3a and 3b are reported for the first time in this study.eninfo:eu-repo/semantics/closedAccess2-HydroxybenzothiazolephosphazeneshexachlorocyclotriphosphazeneSpiro phosphazenesArticle199427728210.1080/10426507.2024.23186002-s2.0-85193783712Q4WOS:001229180400001N/A
