摘要:Process for the synthesis of alpha -chlorinated chloroformates, and new alpha -chlorinated chloroformates. The invention relates to a new process for the manufacture of alpha -chlorinated chloroformates and, to new alpha -chlorinated chloroformates as new industrial products. The process according to the invention consists of a synthesis, by catalytic phosgenation, of alpha -chlorinated chloroformates of the formula: in which: R represents a substituted or unsubstituted hydrocarbon radical and m represents an integer superior or equal to one, this synthesis consisting in reacting phosgene with the aldehyde R-CHO)m, in the presence of a catalyst which is an organic or inorganic substance which is capable in a medium containing an aldehyde of the formula R-CHO)m, phosgene and, possibly, a solvent, of generating a pair of ions one of which is an halogenide anion and the other is a cation which is sufficiently separated from said halogenide anion so as to give to the latter a nucleophilic power enabling it to react with the function(s) aldehyde of the molecule R-CHO)m.

摘要:In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a Ï€-donor conjugated to a Ï€-acceptor through a Ï€-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore-containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.
