Abstract:
A lithographic printing plate precursor comprises an imageable layer comprising a free radically polymerizable component, an initiator composition capable of generating free radicals upon exposure to imaging infrared radiation, an infrared radiation absorbing dye that is defined by Structure (I) shown in the disclosure, which dyes comprise one or more ethylenically unsaturated polymerizable groups in an organic group that is attached to the methine chain. These infrared radiation absorbing dyes exhibit a reduced tendency to crystallize in the imageable layers in the presence of tetraaryl borate counter anions and therefore provide improved shelf life.
Abstract:
A process for forming an aryl-aryl bond comprises the step of reacting an arene hydrocarbon compound with either (1) an organic oxidant selected from the group consisting of a quinone, a quinone imine, a quinone diimine, and a nitroarene, or (2) an oxidizing salt selected from the group consisting of a triarylaminium salt, an oxonium salt, and a nitrosium salt, or (3) a hypervalent iodine compound, each in the presence of a Brönsted or Lewis acid.
Abstract:
Compounds of formula (I), ##STR1## in which R.sub.1 and R.sub.2, which may be the same or different, represent hydrogen, C.sub.1-6 alkyl, R.sub.3 and R.sub.4 independently represent one or more radicals selected from hydrogen, OH, NH.sub.2, NO.sub.2, halogen, C.sub.1-6 alkyl or C.sub.1-6 alkoxy and n is an integer from 1-2 inclusive, and pharmaceutically acceptable derivatives thereof are useful as pharmaceuticals; in particular, they possess N-methyl-(d)-aspartate(NMDA) blocking properties and are useful in the treatment and/or prevention of neurodegenerative conditions.

Abstract:
Compounds of formula I ##STR1## wherein R, R.sup.1, R.sup.2, and R.sup.3 and A are as defined herein, together with pharmaceutically acceptable salts, enantiomers or tautomers are useful as pharmaceuticals, particularly in the treatment of inflammatory disease.
