Abstract
Bis{[1-(2-A-2-B)ethenyl]} [2-R.sup.2 -4-X-phenyl- or 1-(2-R.sup.2 -4-X-phenyl) ethenyl]methanes useful as color formers, particularly in transfer imaging, pressure sensitive and thermal-responsive carbonless duplicating systems, are prepared by the interaction of two molecular proportions of the corresponding 1-A-1-B-ethene with the appropriate 2-R.sup.2 -4-X-phenyl-(CH.dbd.CH).sub.n --CHO presence of an acidic catalyst.

A bis [1-(2-A-2-B)ethenyl][2-R.sup.2 -4-X-phenyl or 1-(2-R.sup.2 -4-X-phenyl)-2-ethenyl] methane having the formula ##STR8## wherein:
- A represents a moiety selected from the group consisting of ##STR9## B represents a moiety selected from the group consisting of ##STR10## in which X represents hydrogen, --N(R)(R.sup.1), a pyrrolidinyl or piperidinyl;
- Y represent hydrogen or --N(R.sup.3) (R.sup.4);
- Z represents hydrogen or --N(R.sup.9) (R.sup.10) wherein R, R.sup.3 and R.sup.9 independently represent hydrogen;
- non-tertiary C.sub.1 to C.sub.8 alkyl;
- benzyl;
- or benzyl substituted in the benzene ring by one or two of non-tertiary C.sub.1 to C.sub.4 alkyl, non-tertiary C.sub.1 to C.sub.4 alkoxy, nitro or halo;
- R.sup.1, R.sup.4 and R.sup.10 independently represent non-tertiary C.sub.1 to C.sub.8 alkyl;
- phenyl;
- phenyl substituted with one or two of non-tertiary C.sub.1 to C.sub.4 alkyl, non-tertiary C.sub.1 to C.sub.4 alkoxy, nitro or halo;
- benzyl;
- or benzyl substituted in the benzene ring by one or two of non-tertiary C.sub.1 to C.sub.4 alkyl, non-tertiary C.sub.1 to C.sub.4 alkoxy, nitro or halo;
- R.sup.2, R.sup.5 and R.sup.11 independently represent hydrogen, non-tertiary C.sub.1 to C.sub.4 alkyl, non-tertiary C.sub. 1 to C.sub.4 alkoxy or halo;
- R.sup.6 and R.sup.12 independently represent hydrogen;
- non-tertiary C.sub.1 to C.sub.16 alkyl substituted by non-tertiary C.sub.1 to C.sub.8 alkoxy, phenoxy, phenyl or phenyl substituted by one or two of non-tertiary C.sub.1 to C.sub.4 alkyl, non-tertiary C.sub.1 to C.sub.4 alkoxy, nitro or halo;
- R.sup.7 and R.sup.13 independently represent hydrogen, non-tertiary C.sub.1 to C.sub.4 alkyl or phenyl;
- R.sup.8 and R.sup.14 independently represent one or two of hydrogen, non-tertiary C.sub.1 to C.sub.4 alkyl, non-tertiary C.sub.1 to C.sub.4 alkoxy, nitro or halo;
- and n represents zero or one with the proviso that only one of X, Y and Z can be hydrogen at the same time.
A compound of the formula:
- ##STR11## wherein X is selected from phenyl, and para substituted phenyl, in which the substituent is selected from NR.sup.7 R.sup.8 ;
- and each Q is H;
- each R.sup.1 and R.sup.2 is independently H, C.sub.1-4 -alkyl, trimethylene or C.sub.1-4 alkyl-substituted trimethylene which is also attached to an ortho carbon atom of the adjacent benzene ring;
- each R.sup.3 and R.sup.4 is independently H, C.sub.1-4 -alkyl, trimethylene or C.sub.1-4 alkyl-substituted trimethylene which is also attached to an ortho carbon atom of the adjacent benzene ring;
- each R.sup.7 and R.sup.8 is independently H, aryl, C.sub.1-4 -alkyl, substituted C.sub.1-4 alkyl trimethylene or C.sub.1-4 alkyl-substituted trimethylene which is also attached to an ortho carbon atom of the adjacent benzene ring;
- and wherein each benzene ring has no further substitutents.
The compound 1,1,3,5,5-Penta(4-[N,N-dimethylamino]phenyl)-pentadi-1,4-ene.
