| Popis: | Mechanochemical synthesis of a series of Zn and Pd dialkyl 2,2′-bipyridine-4,4′-dicarboxylate complexes (Ln, where n specifies the number of carbons in the α- or β-substituted alkyl chains) including ZnLβ12Cl2, ZnLβ14Cl2, ZnLα14Cl2, ZnLα14I2, and PdLα14Cl2 is explored through a variety of linear and sigmoidial reaction models. The Johnson-Mehl-Avrami-Yerofeev-Kolmogrov (JMAYK) and Finke-Watzky (FW) models are largely equivalent as demonstrated through analysis of Akaike weights. This analysis was extended to the previously reported syntheses of PdLβ10I2, PdLα16I2, and PdLβ16I2 with similar results, except that the JMAYK model is significantly superior to the FW model for PdLβ16I2. The physical properties of the reaction mixture, most prominently whether the product phase is easily mixed, is a major factor in determining the rate of reaction. |
