Abstract:
A compound having the formula: ##STR102##whereinR.sup.1 is selected from the group consisting of hydrogen, methyl, ethyl, 2,2,2-trichloroethyl, 2-(trimethylsilyl)-ethyl, 2-(phenylthio)-ethyl, propyl, isopropyl, n-butyl, t-butyl, allyl, 1-isopropyl allyl, cinnamyl, 4-nitrocinnamyl and a substituted benzyl of the formula: ##STR103##whereinthe atom or group represented by each of a-e is the same or different and is independently selected from the group consisting of F, Cl, Br, I, hydrogen, methyl, ethyl, isopropyl, n-butyl, t-butyl, phenyl, methoxy, ethoxy, NO.sub.2,--SO.sub.3 H, --CN, --SCH.sub.3, and --(O)SCH.sub.3 such that at least one of the atoms or groups represented by a-e is not hydrogen; andthe atom or group represented by each of g-h is the same or different and is independently selected from the group consisting of hydrogen and methyl; andR.sup.2 is independently selected from the group consisting of methyl, ethyl, 2,2,2-trichloroethyl, 2-(trimethylsilyl)-ethyl, propyl, isopropyl, n-butyl, t-butyl, allyl, 1-isopropyl allyl, cinnamyl, 4-nitrocinnamyl, a substituted benzyl as set forth above, a diphenylmethyl group of the formula: ##STR104##wherein each of A.sub.1 -A.sub.10 is independently selected from the group consisting of F, Cl, Br, I, hydrogen, methyl, ethyl, methoxy and ethoxy, andR.sup.4 is selected from the group consisting of hydrogen, methyl and ethyl;a thioether group of the formula: ##STR105##whereinR.sup.5 is selected from the group consisting of methyl, ethyl, propyl, isopropyl, n-butyl, t-butyl and a phenyl group,whereinthe phenyl group is a group of the formula: ##STR106##wherein the atom or group represented by each of i-m is the same or different and is independently selected from the group consisting of F, Cl, Br, I, hydrogen, methyl, ethyl, isopropyl, n-butyl, t-butyl, phenyl, methoxy, ethoxy, NO.sub.2, --SO.sub.3 H, --CN, --SCH.sub.3, and --(O)SCH.sub.3 ; anda substituted ethyl group of the formula: ##STR107##wherein W is selected from the group consisting of cyano, alkylsulfonyl, arylsulfonyl, phenyl, p-nitrophenyl, o-nitrophenyl, and p-alkylsulfonylphenyl; andR.sup.6 -R.sup.8 are the same or different and are independently selected from the group consisting of hydrogen, methyl, ethyl, n-propyl, isopropyl, n-butyl and t-butyl.
