  • Process for the preparation of ethynylbenzaldehydes
    Patent number: 4849546
    Abstract: A multi-step process for the preparation of ethynylbenzaldehydes from bromo- or iodobenzaldehydes is disclosed. The arylhalogen is replaced with a protected ethynyl compound which is subsequently cleaved by base to form the arylacetylene. The aldehydic functionlity is preserved by formation of a corresponding Schiff's base or acetal, and its subsequent regeneration by treatment with aqueous acid.

  • Phenylacetylene-substituted Schiff's base monomers and electroconductive polymers
    Patent number: 4730032
    Abstract: Novel mono- or difunctional phenylacetylene-substituted Schiff's base monomers useful in the preparation of electrically conducting polymers is disclosed. On heating, these monomers melt to a viscous liquid state, and on continued heating above about 300.degree. C. polymerize to form an electrically insulating thermoset polymer. On further post-cure heat treatment, the polymer becomes electroconductive showing a bulk conductivity of at least 10.sup.-2 S/cm.

  • Monomeric disulfonimides
    Patent number: 4510324
    Abstract: The invention provides disulfonimide compounds of the general formula ##STR1## wherein X is bromine, chlorine or iodine; R is hydrogen or methyl; and R' is alkyl, aryl or substituted aryl. The compounds are useful as activators for anaerobic adhesive compositions and also as intermediates in the preparation of monomers of the general formula ##STR2## wherein R and R' are as defined above. The monomers are polymerizable to form homo- and copolymers useful in the photographic industry as well as in formulating anaerobic adhesive compositions.
