ABSTRACT:
Spirotetrathiocarbamates (STOCs) or oxa substituted compounds (SOTOCs) of Formula I: Formula (I) or bisSTOC or bisSOTOC compounds of Formula II: Formula (II) wherein X1, X2, X3, X4, X5, X6, X7, and X8, are independently O or S; and preferably at least two and up to all four of X1, X2, X3and X4, and at least two and up to all four of X5, X6, X7, and X8are sulfur; Z is —CmR22mwherein m=1 to 4; —C(R2)2SC(R2)2—, C(R2)2SSC(R2)2—, or —C(R2)OC(R2)2; n is from 0 to 4; M is selected from CH2Cl, CH2SC(O)R1, CH2SC(S)R1, CH2S(CH2CH2S)qH wherein q is 0, 1 or 2; —CR2═CH2, —CH2OC(O)CR2═CH2, CH2N═C═S, CH2N═C═O, CH2NR2H, CH2OH, CH2SCH2CH2CR2═CH2, phenyl, C(R2)phenyl, furan, thiophene, halogen, C3-C6cycloalkyl, C3-C6heretocyclics, thiol, H, (III) or (IV) wherein A is S, O or phenyl; x is 0 or 1; R1is C1-C22alkyl; and R2is H or C1-C22alkyl have excellent optical properties. Methods for preparing these compositions and optical lenses prepared from the compounds are also provided.
