Ferrocenylaryl or ferrocenylheteroaryl phosphines bearing a carboxaldehyde group, rac-[Fe{η5-1-PPh2(spacer)-2-NMe2CH2C5H3}(η5-C5H4CHO)] (12-15, spacer = bond, 1,4-C6H4, 1,3-C6H4, 2,5-thiophenediyl), were prepared in a facile four-step sequence starting with dibromination of N,N-dimethylaminomethylferrocene (1) followed by Negishi cross-coupling between 1,1′-dibromo-2-N,N-dimethylaminomethylferrocene (rac-2) and bromoaryl or bromoheteroaryl phosphine oxides, Br-spacer-P(O)Ph2 (spacer = 1,4-C6H4, 1,3-C6H4, 2,5-thiophenediyl), reduction with trichlorosilane, and functionalization of the 1′-position of the cyclopentadienyl ring. All products were fully characterized by spectroscopy (1H, 13C, and 31P NMR, MS, IR) and for 3, 7 and 11 also by x-ray crystallog. Furthermore, preliminary studies on the grafting of 12 on silica were conducted. In the experiment, the researchers used many compounds, for example, (3-Bromophenyl)diphenylphosphine oxide(cas: 10212-04-1Related Products of 10212-04-1)
(3-Bromophenyl)diphenylphosphine oxide(cas: 10212-04-1) belongs to mono-phosphine Ligands.Phosphine ligands are the most significant class of ligands for cross-coupling because of the alterability of their electronic and steric properties. Ligands play a key role in stabilizing and activating the central metal atom and are used in reactions, such as transition metal catalyzed cross-coupling.Related Products of 10212-04-1
