外文摘要：Ultra-long n-alkanes are highly valuable in both scientific research and as major constituents of specialty high-melting-point waxes.Unlike conventional methods(e.g.,Fischer-Tropsch(FT),ethylene oligomer-ization,and polyethylene cracking)typically resulting in wide n-alkane distributions,the elaborate design strategy presented herein allows the direct synthesis of pure,long n-alkanes using a modular splicing method with acetone,furfural,and fatty acid anhydrides or acyl chlorides as bio-blocks.The herein approach is based on a simple four-step catalytic reaction scheme involving C-C chain elongation and C-O bond activation.The synthesized pure n-alkanes had a carbon chain length as high as C49(total yield of 49％).The synthesis approach also allows to selectively prepare n-alkanes with even and odd car-bon numbers ranging from C15 to C49.This process represents a great breakthrough in the synthesis of long-chain pure n-alkanes,surpassing the carbon number limitations reported in previous methodologies.
