Concept explainers
(a)
Interpretation:
If the given compound must be synthesized using compounds with six or fewer carbons, it is to be determined which carbon–carbon bond-forming reaction from Table 19-1 should be incorporated in the synthesis.
Concept introduction:
The carbon–carbon bond-forming reaction results in heteroatoms having a specific relative positioning along the carbon backbone. If the heteroatoms in a target have 1, 2-, 1, 3-, 1, 4-, or 1, 5- relative positioning and the synthesis calls for a carbon–carbon bond-forming reaction, then consider using a corresponding reaction from Table 19-1. In a retrosynthetic analysis, therefore, apply a transform that takes our target molecule back to reactants. Disconnect the appropriate C-C bond to take back to reactants.

If the given compound must be synthesized using compounds with six or fewer carbons, it is to be determined which carbon–carbon bond-forming reaction from Table 19-1 should be incorporated in the synthesis.

Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
