Main observation and conclusion The first example of Rh-catalyzed kinetic resolution of 1,3-disubstituted allene-1,3-dienes involving intramolecular[4+2]-cycloaddition has been developed.Followed by C=C isomerization,...
A new crystal form of diammonium 5,5'-bistetrazole-1,1'-diolate (1) was prepared by two novel methods and fully characterized by using IR, NMR spectroscopy, elementary analysis, single crystal X-ray crystallograph...

Chiral diphosphite ligands were prepared by the reaction of (1R,5S,6R)-(trans,trans)-spiro[4.4]nonane-1,6-diol with chlorophosphites. The rhodium(I) complexes containing these ligands were tested in the asymmetric hyd...
In a search for novel agrochemical with high activity and low toxicity,a series of substituted 4,5 -dihydro-imidazol-5-one containing selenomorpholine group were synthesized by a three-step synthetic route starting ...
