摘要:
Provided is, as a radioactive halogen labeling precursor compound that is highly reactive and stable, a compound represented by the following general formula (II):
wherein R1 and R2 each independently represent an alkyl group having 5 to 20 carbon atoms, X1 and X2 each independently represent a halogen atom, and R3 represents a monovalent group derived from a sugar, or the like.

Nonlinear optical (NLO) compositions are disclosed which contain polar disulfone-functionalized molecules (PDFMs) incorporated in a polymeric material. when aligned noncentrosymmetrically in the polymeric material, the PDFMs generate a second-order NLO response. There is also disclosed: a method of preparing a NLO composition; novel PDFMs and novel polymers; and a new process for preparing PDFMs.
摘要:
A process for preparing polar disulfone-functionalized molecules, which process comprises performing one or more of the following reactions:(i) reacting a vinyl ether disulfone molecule with an activated aromatic molecule, an activated heterocyclic molecule, a dye base, or a dye olefin;(ii) reacting an enamine disulfone molecule with a dye base or a dye olefin; and(iii) reacting an alkenyl disulfone molecule having a vinylogous methyl or methylene group conjugatively located relative to the disulfone group with an aldehyde or an acetal derived from an aldehyde.

摘要:
The synthesis of novel ethanesulfonamide compounds is described. The novel ethanesulfonamide compounds have antisecretory activity and are used in the treatment of peptic ulcer disease. The intermediates used to prepare the ethanesulfonamides are useful in the treatment of osteoporosis and other bone wasting diseases.
摘要:
Chlorosulphonyl vinyl isocyanates are produced by reacting either an Alpha -halogenated isocyanide dichloride or an Alpha , Beta -unsaturated isocyanide dichloride with a halogen sulphonic acid. The chlorosulphonyl vinyl isocyanates produced are useful in the preparation of plant protection agents, dyestuffs and detergents and as monomers for the production of plastics.
