    摘要: In the presence of an imide compound of the following formula (1), a sulfur oxide is reacted with an organic substrate to yield a corresponding sulfur acid or its salt. This process can efficiently produce an organic sulfur acid or its salt under relatively mild conditions. ##STR1## wherein each of R.sup.1 and R.sup.2 is, identical to or different from each other, a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cycloalkyl group, a hydroxyl group, an alkoxy group, a carboxyl group, an alkoxycarbonyl group, or an acyl group, where R.sup.1 and R.sup.2 may be combined to form a double bond or an aromatic or non-aromatic ring; X is an oxygen atom or a hydroxyl group, where one or two N-substituted cyclic imido groups indicated in the formula (1) may be further bonded to the aforementioned R.sup.1, R.sup.2 or to the double bond or aromatic or non-aromatic ring formed together by R.sup.1 and R.sup.2.

    摘要: The invention relates to new 3-benzylidene-camphor derivatives of the formula: ##STR1## in which R.sub.1 denotes H or SO.sub.3.sup..crclbar. M.sup..sym., with M=H, an alkali metal or N.sup..sym. (R.sub.3).sub.4, with R.sub.3 =H or C.sub.1 -C.sub.4 alkyl or hydroxyalkyl; R.sub.2 denotes C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy and n=0-4; and Z denotes ##STR2## in which R.sub.4 has the same meaning as R.sub.1 and can be identical or different, or alternatively ##STR3## in which R.sub.5 denotes H, optionally substituted aryl, C.sub.1 -C.sub.4 alkyl, --CN, --C00R7 or ##STR4## and R.sub.6 denotes --COOR.sub.8 or ##STR5## in which R.sub.7 and R.sub.8, which are identical or different, denote alkyl, alkenyl, cycloalkyl or aralkyl and R.sub.9 and R.sub.10, which are identical or different, denote H, alkyl, alkenyl or cycloalkyl; if R.sub.5 =H, alkyl or aryl, R.sub.6 can represent --COO.sup..crclbar. M.sup..sym. ; the methylidene-camphor radical, on the one hand, and the radical Z, on the other hand, are in the meta or para position. These derivatives act as sun filters.
