Related Products of 12150-46-8, 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.12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a patent, introducing its new discovery.
The complexes [Cu2(dppa)3(CH3CN)2][BF4]2 (1) and Cu2(dppa)3(O3SCF3)2 (2) have been prepared in good yields by treating [Cu(MeCN)4][BF4] and [Cu(MeCN)4][O3SCF3], respectively, with Ph2PC{triple bond, long}CPPh2 (abbreviated as dppa) at room temperature. The reaction of 1 with di-2-pyridyl ketone (abbreviated as dpyk) produces [Cu2(dppa)2(dpyk)2][BF4]2 (3), and with 1,1?-bis(diphenylphosphino)ferrocene (abbreviated as dppf) produces [Cu2(dppa)(dppf)2][BF4]2 (4). The molecular structures of 1-4 have been determined by an X-ray diffraction study. Compounds 1 and 2 form a helical Cu2(dppa)3 metallatricycle, compounds 3 forms a Cu2(dppa)2 metallacycle, and compound 4 contains a linear Cu2(dppa) skeleton.
