Abstract
Official abstract text for this publication.
Compounds 1,3,4-(SiMe 3 )(C 6 F 5 )(alkyl)C 5 H 3 are made using a simplified synthetic strategy which is readily scalable. On reaction with a suitable transition metal species, a 1,3,4-(SiMe 3 )(C 6 F 5 )(alkyl)C 5 H 3 molecule provides an organotransition metal complex comprising a 1,2-(C 6 F 5 )(alkyl) substituted cyclopentadienyl ligand, which is active toward olefin polymerization.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for making the compound 1,3,4-(SiMe 3 )(C 6 F 5 )(R)C 5 H 3 without isolating intermediates, said method comprising the following steps: Step 1) in the presence of an ethereal solvent, combining perfluorobenzene C 6 F 6 , a metal cyclopentadienide [M 1 ][C 5 H 5 ] and a first base M 2 B 1 to form a first reaction mixture comprising [M 1 /M 2 ][C 6 F 5 )C 5 H 4 ]; Step 2) combining at least 2 molar equivalents of CISiMe 3 with said first reactio…
