New Sulfur-Containing [4.5]-Spiroheterocycles The thermal reaction of the [4.5]-spirocyclic compound 1,3,6,8,10-pentamethyl-1,3,6,8, 10-pentaazaspiro[4.5]decane-2,4,7,9-tetrone with tetraphosphorus decasulfide leads to the complete series of mono- to tetrathiones. The sulfuration occurs at first at the five-membered cycle of the spiro-system. The formation of isomers is not observed.
