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...

(1) Two thioalkynes couple via the triple bond according to a classical reaction type. However, the alkyne asymmetry yields three types of coupling which were all observed. (2) The particular role of sulfur is displayed first by the cleavage of one or the other carbon-sulfur bond, or more...
Variation in the leaving group from Cl to I causes the elongation of the Cα-Y bond ∆L (LCα-I − LCα-Cl) ranging from 0.26, 0.29, 0.32 to 0.38Å with n going from 0 to 3 for the TS structure of inv-SN2. Similarly, the bond elongation ∆L of Cα-Y for anti-E2 ...
