Infrared liquids

For twice-distilled material infrared (liquid film) cm." 1745 strong, 1565 strong, 1430 medium strong proton magnetic resonance (chloro-form-d) (number of protons, multiplicity, coupling constant J in Hz) 3.14-3.45 (1, multiplet), 3.76 (3, singlet), 3,86 (3, singlet), 5.6 (1, doublet of doublets, J = 6 and 8). [Pg.62]

The mixture was characterized as follows infrared (liquid film) cm. 1745 strong (shoulder at 1720), 1640 medium strong, 1440 medium strong proton magnetic resonance (chloroform-d) B (multiplicity, number of protons) 3.75 (singlet, 6), 4.12 (singlet, 2), 6.21 and 6.30 (two singlets, 1). [Pg.65]

The product was further characterized as follows infrared (liquid film) cm. 2195 strong, 1370 strong, 1170 strong proton magnetic resonance (chloroform-d) S 3.43 (singlet). [Pg.90]

Distillation is unnecessary since the product is pure by spectral criteria. Infrared (liquid film) cm.-1 1730, 1555 proton magnetic resonance (CDCI3) 8, number of protons, multiplicity 1.30 (3, triplet, CH2C/73), 4.30 (2, quartet, Cf/2CH3), 4.8-5.2 (3, multiplet). [Pg.67]

To extend the comparison between homogeneous and supported systems, we have carried out kinetic measurements on the reactions of polymer-supported [Rh(CO)2I2] complexes with Mel. In order to monitor the reactions in situ, polymer films were inserted between the windows of a conventional infrared liquid cell, fitted with a thermostatted jacket. The cell was then filled with neat Mel or a solution of Mel in CH2C12, and transmission spectra recorded directly through the polymer film immersed in the Mel solution. An example of a series of spectra recorded in this way is shown in Figure 5. The absorption bands of [Rh(CO)2I2] are replaced cleanly by those of the product acetyl complex, [Rh(CO)(COMe)I3], with the high frequency band of the reactant almost coinciding with the terminal v(CO) band of the product. [Pg.172]
