1003 Although HSiO-will not transfer a hydride to acetone (HA = 39.6 kcal mol-I), acetaldehyde (HA = 40.7 kcal mol-'), or ben-zaldehyde (HA = 45.9 kcal mol-'), hydride transfer to acrylonitrile (HA = 57.6 kcal mol-') and acrolein (HA = 61.5 kcal mol-') is observed. Hydride transfer to C 0 2 (HA = 5 1.6 kcal mol-') leads to an ion of mass 45, the same mass as HSiO-; however, experiments with I3CO2 resulted in an ion of mass 46 (HI3CO2-) indicating hydride transfer. Therefore, the hydride… CONTINUE READING

It also is possible to bracket the proton affinity of the HSiO - anion and , as a result , determine the heat of formation of its parent ( H2Si0 or HSiOH).29 This procedure is complicated because ( 28 ) Hydride affinities are taken from a compiliation provided by Squires , we have a minor H3SiO - contamination , and HSiO - reacts with standard acids in ways other than proton transfer .
