Phosphorus compounds, infrared spectra

Hydrolysis of diazepine 85 gave rise to 1,4-diaminobutane71,72 while treatment of 85 with phosphorus pentasulfide gave 92.7 4 The infrared spectrum of 85 has been studied.99 100 In studies carried out on the molten monomer, 92 polymerized but 85 did not.101 Condensation of 92 with formaldehyde gave the bis compound (103) but no... 

Figure 4.9 below shows the spectrum of a phosphorus compound with the empirical formula C2H7PO3. Assign the major infrared bands in this spectrum. 

The infrared spectra of many organocopper compounds have been reported (40, 41, 73, 75, 77) and compared favorably with the respective covalently bound organic halides. Bidentate phosphorus ligands coordinate more strongly with arylcopper compounds than monodentate ligands (41, 75, 281e). Substantial modification of the ligand spectrum is also seen in the infrared spectra of arylcopper complexes with bipy-ridyl or 1,10-phenanthroline (41).
