Geminal disubstitution on silicon in dialkylsilylene-spaced divinylarene copolymers may dictate the conformation and photophysical properties of the copolymers, bulky (i)Pr substituted copolymers being more folded than Me substituent analogues.
In situ prepared chromium catalysts containing bulky diphosphinoamine (PNP) ligands, upon activation with MAO, are extremely efficient catalysts for the trimerisation of ethylene to 1-hexene.
Terminal, 4-coordinate phosphinidenes of Ta supported by bulky anilide ligands are prepared by an apparent reaction sequence involving metallaziridine phosphanide complexes.
Some sterically hindered N-substituted derivatives of daunorubicin are known to be poor substrates for NADH dehydrogenase, NADPH cytochrome P450 reductase and xanthine oxidase. In consequence, poor oxygen radical generation by these compounds is observed. In this study we examined a new family of sugar-N-substituted derivatives of daunorubicin bearing a bulky substituent introduced on the nitro...
The title compound, C(22)H(14)F(3)N(3), is a versatile tridentate N-donor ligand consisting of a terpyridyl (terpy) molecule substituted in the 4'-position by a phenyl group, itself substituted in an ortho-position by a bulky trifluoro-methyl group. The phenyl ring is twisted as a result of steric inter-actions involving the bulky trifluoro-methyl substituent. This is reflected in the dihedral ...
