Amino-functionalization of large-pore mesoscopically ordered silica by a one-step hyperbranching polymerization of a surface-grown polyethyleneimine.

A simple method for surface functionalization of large-pore mesoporous silica by hyperbranching polymerization resulting in a high loading of amine groups is presented.

Indenyl esters as potential electronically modified cyclopentadienyl ligands for transition metal complexes

Abstract The preparation of two new indenyl esters 2-(2,4,6-trimethylbenzoyloxy)indene ( 1 ) and 2-(adamantanoyloxy)indene ( 2 ) is reported. Both compounds can be deprotonated with alkyllithiums such as n -BuLi and the resulting anions trapped by addition of TMSCl or iodomethane, rendering them as potential electronically modified cyclopentadienyl ligand analogues for complexation with transition metals.
