Abstract: Vinyl glyoxal derivs. of formula (Ia) are new: R' = 1-20C alkyl, 2-20C alkenyl, 3-7C cycloalkyl, or phenyl opt. substd. by 1-12C alkyl, 1-12C alkoxy, halogen, CN or CF3. Prodn. of vinyl glyoxal derivs. of formula (I) is effected by (a) reacting of formula R''CHO (III) in the presence of a catalyst to form acyloins of formula (IVa) and/or (IVb); (b) oxidising (IV) to the corresp. dicarbonyl cpd. (V); and (c) subjecting (V) to gas-phase pyrolysis at 500-700 deg. C under reduced pressure, esp. below 0.1 mbar: R = alkyl, alkenyl, cycloalkyl or opt. substd. phenyl; R'' = R or bicyclo(2,2,1)hept-5-en-2-yl.

Abstract: Methine dyes have the polyketone grouping (I), in which the variables have the following meaning: A represents (a) or (b); R represents a 5 or 6-membered cycloaliphatic residue with one or two heteroatoms from the group -NR -, -O- and -S-, that can be annelated with an iso-or heteroaromatic group, whereas R represents C5-C7 cycloalkyl or phenyl, that can carry as substituents halogen, C1-C4 alkyl or C1-C4 alkoxy; C1-C20 alkyl, the C chain of which can be interrupted by one to five ether function oxygen atoms and that can carry the following substituents: hydroxyl, phenyl, 1,3-dioxan-2-yl, 1,3 dioxolan-2-yl, -NHR , -NHCOR , -CONHR , -OCONHR , -N (R )3.An , -SO3H or -SO3 Ka , where R represents one of the unsubstituted or hydroxyl- or phenyl-substituted alkyl residues R or phenyl, whereas the residues R may be different or the same when they represent -N (R )3, and An is an anion equivalent and Ka is cation equivalent; R , R can be different or identical C1-C10 alkyl groups or can form together a residue R ; m, n identical or different integers from 0 to 3. These dyes are useful as medicaments, for generating singlet oxygen, as sensitizers in electrophotographic layers and for photopolymerizations, and as laser light-sensitive dyes in optical recording media; also disclosed are new triketomethine and tetraketomethine dyes.

Abstract: Vinylglyoxal derivatives of the general formula I (I) 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 (V) is either (a) subjected to autocondensation with formation of a compound of the formula VII (VII) or (b) reacted with a compound of the general formula II R-CH=O (II) where R has the above meanings, with formation of a mixture of the compounds of the general formulae VIII (a) and (b) (VIIIa) (VIIIb) 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 DEG to 700 DEG C. and under reduced pressure, in particular less than 10-1 mbar, and, if desired, the resulting compound of the general formula I is further purified. These compounds can be used, for example, as monomer components in polymeric systems.
