摘要：

Heterogeneous catalysts have so far not been very efficient [turnover, frequency (TOF) < 19 h(-1)] or very selective (<= 60%) for alpha-olefin formation in deoxygenation of fatty acids. Here we report more than 20-fold higher activity (TOF = 420 h(-1)) and high selectivity (>95%) for one such deoxygenation, decarbonylative dehydration, by using a heterogeneous Pd/C catalyst in the presence of phosphine ligands. The process is solvent free, allows for catalyst recycling, and does not require in situ distillation of the product to maintain high selectivity.
