Choudhary, Deepika,Agrawal, Chanchal,Khatri, Vineeta,Thakuria, Ranjit,Basak, Ashok K.
supporting information, p. 1132 - 1136 (2017/03/02)
N-tosylhydrazones derived from a wide variety of aryl, alkyl and heteroaryl aldehydes undergo smooth coupling with 5,5-dimethylcyclohexane-1,3-dione under transition metal and base free conditions to generate tetraketo compounds in high yields. In presenc
A Self-Assembled Trigonal Prismatic Molecular Vessel for Catalytic Dehydration Reactions in Water
Das, Paramita,Kumar, Atul,Howlader, Prodip,Mukherjee, Partha Sarathi
, p. 12565 - 12574 (2017/09/18)
A water-soluble Pd6 trigonal prism (A) was synthesized by two-component coordination-driven self-assembly of a PdII 90° acceptor with a tetraimidazole donor. The walls of the prism are constructed by three conjugated aromatic buildin
