Up to 50% of the organics in the Murchison meteorite, possibly including some of the polymer, is released in high temperature and pressure aqueous environments, to 350 degrees C and 250 bar, that simulate submarine volcanic, hydrothermal or impact-in

Irradiation of N 2 F 4 (NF 2 ) with propene and with 1,1-difluoroethene in the gas phase atroom temperature leads to the addition of F and NF 2 across the double bond. The ratioof terminal to internal addition of F to propene was found to be 1.4:1 af
