cryogenuc organic chemistry

Anyone aware of a book of cryogenic organic syntheses? Also, what is the
current method of producing cryogenic hydrogen?

Steam reduction of methane (natural gas) produces the hydrogen, a
bulk process used by the oil and plastics industry. Compressors and
heat exchangers refrigerate the hydrogen. (Liquid oxygen is derived
directly from the air by the same process.)

Organic synthesis at very low temperatures is possible by input of
solar ultraviolet radiation which converts simple hydrocarbons like
methane into more complex molecules. Lightning discharge in a similar
environment on even the cold gas giants can produce more complex
hydrocarbons.

So far as we know, biological processes at very low temperatures are
not possible.
