Alright, here's some:
Furthermore, research has documented that "unless the origin of life took place extremely rapidly (in less than 100 years), we conclude that a high temperature origin of life... cannot involve adenine, uracil, guanine or cytosine" because these compounds break down far too fast in a warm environment. In a hydrothermal environment, most of these compounds could neither form in the first place, nor exist for a significant amount of time (Levy and Miller, p. 7933).
As Levy and Miller explain, "the rapid rates of hydrolysis of the nucleotide bases A,U,G and T at temperatures much above 0° Celsius would present a major problem in the accumulation of these presumed essential components on the early earth" (p. 7933).

Furthermore, the authors found that, given the minimal time perceived to be necessary for evolution to occur, cytosine is unstable even at temperatures as cold as 0º C. Without cytosine neither DNA or RNA can exist.

According to this, there is absolutely no chance that the chemicals created by "random chance occurences" could even exist long enough to aid in the production of DNA.
