Compounds for mass coloration of high temperature polymers

The invention relates to novel soluble pigment precursors possessing not only higher thermal stability but also improved solubility characteristics and to a process for mass coloration of high temperature polymers that utilizes these novel soluble pigment precursors. The pigment precursors of the invention are essentially of the formula A(B)x??(I) where x is an integer from 1 to 8, A is the radical of a chromophore of the quinacridone, anthraquinone, perylene, indigo, quinophthalone, indanthrone, isoindolinone, isoindoline, dioxazine, azo, phthalocyanine or diketopyrrolopyrrole series, this radical being linked with xB groups via one or more heteroatoms, these heteroatoms being selected from the group consisting of N, O and S and forming part of the radical A, and B is hydrogen or a group of the formula although at least one B group is not hydrogen and when x is from 2 to 8 the B groups may be identical or different. E1, E2, R1, R2, R3, R4, R7, R11, R14and G1are as defined in the specification. Also claimed are some materials pigmented according to the invention.

Lewis Acid Mediated α-Alkylation of Carbonyl Compounds, VII. Regio and Position Specific α-tert-Alkylation of Ketones

Structurally different ketones can be alkylated at the α-position via their silyl enol ethers with tert-alkyl halides in the presence of Lewis acids such as titanium tetrachloride (->27 - 35).Concerning the alkylation agent, the position specific introduction of branched and cyclic tert-alkyl groups is possible (->41 - 49).Bridgehead halides of the type 1-adamantyl bromide react analogously (->52 - 61).Silyl enol ethers derived from unsymmetrical ketones react regiospecifically (->63, 64, 66, 67).If the reaction partners contain additional functional groups such as aryl residues (->68, 69) or ester groups (->71) or primary alkyl halides moieties (->73), selectivity in the desired manner is observed. α,α'-Bis-tert-alkylated ketones (74 - 76) are also easily accessible, but not the α,α-isomers.
