The effect of non-thermal microwave on purifying natural graphite was studied. It was found that with existence of microwave field, the carbon content of the product was improved from 95.840% to 99.125% and the result of the purifying was affected by the power of the microwave，the reaction pressure and the reaction time. Add 5% (volume fraction) of hydrofluoric acid in the mixed acid system can improve the carbon content of greater than 99.9% of the natural flake graphite. The use of mixed acid of microwave-assisted purification of natural flake graphite is a better way of producing high-purity graphite.

A redox neutral rearrangement of an allene to a 1,3-diene by means of a unique palladium hydride complex is reported. The palladium hydride complex is generated from a simple Pd0 source and boric acid [B(OH)3], which is typically identified as a waste by-product of the Suzuki–Miyaura reaction. A mechanism for this transformation using this novel palladium hydride complex is presented; using a direct sample loop and flow injection ESI-HRMS analysis we have detected and identified key π-allylpalladium complexes that support the addition of the palladium hydride complex to the allene.
