Abstract
Abstract 1,3-Butadienes which are substituted at both terminal carbon atoms with phenyl, naphthyl, theinyl or furyl groups or one benzoxazolyl group are useful as optical brighteners for detergents. The butadienes, some of which are known, can be obtained by HORNER syntheses.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
A detergent composition consisting essentially of as optical brightener 0.01 to 2% by weight of a compound of the formula (1) A -- CH = CH -- CH = CH -- B (1) in which A is phenyl, naphthyl or 2-thienyl and B is 2-benzoxazolyl or defined as A, which radicals A and B are unsubstituted or substituted by lower alkyl; lower alkoxy; phenyl; lower alkyl substituted by phenyl; chlorine; cyano; lower alkanoylamino; benzoylamino; carboxy or sulfo or a group of the formula --COOR, --CONR.sup.1 R.sup.2, --SO.sub.2 OR, --SO.sub.2 NR.sup.1 R.sup.2, --COR.sup.3 or SO.sub.2 R.sup.4 in which R is lower alkyl or phenyl, which radicals R are unsubstituted or substituted by hydroxy, lower alkoxy, lower dialkylamino or lower trialkylammonium; R 1 and R 2 are hydrogen or lower alkyl or R 1 and R 2 together with the nitrogen are piperidino or morpholino; R 3 is lower alkyl or phenyl and R 4 is lower alkyl or phenyl which radicals R 4 are unsubstituted or substituted by lower dialkylamino, lower trialkylammonium, lower alkanoylamino or sulfo.
Claim 2
Dependent Claim
175 words
