  • Patent number: 5405968
    Abstract: Methine dyes with a polyketo group I ##STR1## where A is ##STR2## R.sup.1 is a 5- or 6-membered cycloaliphatic radical which contains one or two hetero atoms from the group --NR.sup.4 --, --O-- and --S-- and which may be fused to an isoaromatic or heteroaromatic group, R.sup.2 and R.sup.3 are identical or different C.sub.1 -C.sub.10 -alkyl groups or together one of the radicals R.sup.1, and m and n are identical or different integers from 0 to 3, are useful as drugs, for producing singlet oxygen, as sensitizers in electrophotographic layers and for photopolymerizations and as laser light sensitive dyes in optical recording media; also novel triketo- and tetraketomethine dyes.

  • Patent number: 5101032
    Abstract: Cycloalkylidene dyes have the formula ##STR1## where m is 0 or 1,L is a chemical bond or C.sub.1 -C.sub.2 -alkylene, which may be substituted,R.sup.1 is hydrogen, C.sub.1 -C.sub.20 -alkyl, which may be phenyl-substituted, substituted or unsubstituted phenyl, naphthyl or C.sub.3 -C.sub.7 -cycloalkyl,Y is oxygen or two hydrogens,X.sup.1 is oxygen andX.sup.2 is C.sub.1 -C.sub.8 -alkanoyloxy, substituted or unsubstituted benzoyloxy, C.sub.1 -C.sub.6 -trialkylsilyloxy or a radical of the formula OR.sup.1 or NR.sup.2 R.sup.3, where R.sup.1 is as defined above and R.sup.2 and R.sup.3 are identical or different and each is independently of the other C.sub.1 -C.sub.20 -alkyl, which may be phenyl-substituted, substituted or unsubstituted phenyl, naphthyl, or C.sub.3 -C.sub.7 -cycloalkyl or R.sup.2 and R.sup.3 together with the nitrogen atom joining them are saturated heterocyclyl, or else one of R.sup.2 and R.sup.3 is hydrogen, or X.sup.1 and X.sup.
    Type: Grant
    Filed: October 22, 1990
    Date of Patent: March 31, 1992
    Assignee: BASF Aktiengesellschaft
    Inventors: Hans-Dieter Martin, Bernhard Albert, Knut Kessel
  • Patent number: 4894483
    Abstract: Vinylglyoxal derivatives of the general formula I ##STR1## where R is straight-chain or branched alkyl or alkenyl, cycloalkyl or unsubstituted or substituted phenyl, are prepared by a process in which bicyclo[2.2.1]hept-5-enecarbaldehyde of the formula V ##STR2## is either (a) subjected to autocondensation with formation of a compound of the formula VII ##STR3## or (b) reacted with a compound of the general formula IIR-CH.dbd.O (II)where R has the above meanings, with formation of a mixture of the compounds of the general formulae VIII (a) and (b) ##STR4## where R is as defined above, in the presence of a catalyst, and the compound of the formula VII or the compounds of the formulae VIII (a) and (b) is or are oxidized to the corresponding dicarbonyl compounds, after which gas-phase pyrolysis is carried out at from 500.degree. to 700.degree. C. and under reduced pressure, in particular less than 10.sup.-1 mbar, and, if desired, the resulting compound of the general formula I is further purified.
