13406-29-6, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.13406-29-6, Name is Tris(4-(trifluoromethyl)phenyl)phosphine, molecular formula is C21H12F9P. In a patent, introducing its new discovery.
New methods for the synthesis of ArPdL2I (L = tertiary phosphine) complexes
Organopalladium ArPdL2I (L = tertiary phosphine) complexes (1) can be synthesized in one step from the precursors Pd2(dba)3¡¤C6H6 (2) (dba = t,t-dibenzylideneacetone) and (eta3-allyl)PdCp (3) (Cp = eta5-cyclopentadienide). Two advantages over previous synthetic methods are that this route requires only stoichiometric amounts of phosphine and that the desired complexes are easily isolated from reaction byproducts. The scope and generality of these reactions are investigated, and the synthesis of a number of new organic- and water-soluble complexes utilizing this methodology is discussed. Improved syntheses of water-soluble ligands P(C6H5)2(4-SO3KC6H 4) (5) and As(C6H5)2(4-SO3KC6H 4) (6) are presented as well.
