<正>Some reactions of R_3SnM(CO)_5(M = Mn,Re) with CH_3CN or pyridine were investigated to give complexes R_3SnMn(CO)_3LL′or R_3SnMn(CO)_4L by a facile mild me
<正>Twelve 23-esterified silybin derivatives with different patterns of substituents such as aromatic and aliphatic groups(1-12) were designed and synthesized.T
<正>Novel pyrimidine nucleoside-3,5-dicyanopyridine hybrids(4) or pyridine attached acylureas(5) were selectively and efficiently prepared from the reaction of
