Experimental Organosynthesis under deep Crustal and Mantle Pressures

There continues to be considerable interest in understanding the potential for abiotic organosynthesis under deep crustal and upper mantle conditions. The potential of such chemistry occurring naturally over the course of Earth history has relevance to both questions of the origins of life and the possibility of deep reservoirs of hydrocarbons derived from sources other than bio-organic precursors. Over the past several decades numerous experiments have been performed to assess this potential. It has become clear that kinetic barriers are commonly encountered under a wide range of experimental conditions. In this talk we will discuss the effects of inorganic promoters of organic reactions, unexpected pressure effects, and potential importance of metallo-organic intermediates.
