CH3CN + LDA + cyclohexanone = ? LDA是一种碱,CN之间是triple-bond。网上应该都有。 我的结果是6个C的环。一个C连=O,旁边的一个C连-C-CN。结果却不对,求解。不好意思哈,还是不太明白你说的第3步...cyclohexanone便成cyclohexene了?ene or ane?还有H2C=C=N- N上面有2个long pair...而且是负的...

whereas cleaving the CN triple bond needs to overcome a higher activation barrier; hence the generated CN−diffuses away from the PBA lattices, forming VCN(Fig.1;Supplementary Fig.2). Figure2ashows the transmission electron microscopy (TEM) image of the PBA bombarded with N2plasma for 60 ...

“We would support such a move if it benefitted our community,” said a group of parents at Clara Barton Elementary. “Especially if we have to pay for another bond. Our last bond, Measure U, we pay taxes on but only received 17% of that money.” Another parent felt they didn’t ...
