Abstract
The thermodynamic hydride donor abilities of 1-benzyl-1,4-dihydronicotinamide (BzNADH, 59 ± 2 kcal/mol), C5H5Mo(PMe3)(CO)2H (55 ± 3 kcal/mol), and C5Me5Mo(PMe3)(CO)2H (58 ± 2 kcal/mol) have been measured in acetonitrile by calorimetric and/or equilibrium methods. The hydride donor abilities of BzNADH and C5H5Mo(PMe3)(CO)2H differ by 13 and 24 kcal/mol, respectively, from those reported previously for these compounds in acetonitrile. These results require significant revisions of the hydricities reported for related NADH analogues and metal hydrides. These compounds are moderate hydride donors as compared to previously determined compounds.Keywords
