Allene compounds have the formula: in which R is a substituted or unsubstituted mono- or polyvalent benzene, naphthalene, anthracene, azobenzene, bisphenol or polyphenyl (containing 2 to 10 benzene rings connected in line) nucleus, or a group (in which each group Ph is a phenylene, halophenylene, alkylphenylene, cyanophenylene or alkoxyphenylene group, and the chain R1 linking the two group Ph is a C1 -C6 aliphatic hydrocarbon or an alicyclic hydrocarbon group, the chain optionally being interrupted by one or more oxygen atoms); A is a carboxyl or sulphonyl group or a group --CH=C=CH2 ; n is an integer of from 1 to 10; m is 0, 1, 2 or 3; and the sum of m and n is equal to the valence of the group R. They may be prepared by isomerization of corresponding propargyloxy compounds.
