The forward arrow, otherwise known as the “reaction arrow”. Now, “BH3, then Na OH/H2O2” mht not exactly seem like your idea of “action”, but put yourself in the alkene’s position – it’s double bond is being ripped asunder in order to form new bonds to boron and hydrogen, and then with the addition of H2O2, the bond to boron is replaced with one to oxygen.

We value excellent academic writing and strive to provide outstanding essay writing services each and every time you place an order. "Retrosynthesis" means planning a synthesis backwards, by starting at the product, the "target" and taking it back a step at a time to simple, available starting materials or precursors.

  • To my knowledge there are 8 different types of arrows you meet in organic chemistry. That’s a pretty eventful day in the life of an alkene. The single-headed (or “single-barbed”) arrow depicts the movement of a single electron.

    There isn’t any hard and fast rule about what is supposed to go above or below the arrow, although reagents tend to go above and solvents tend to go below. This is often used to show a speculative or theoretical transformation, where conditions mht have yet to be discovered. The curved arrow formalism is such an important tool that entire books have been devoted to it (for instance, I hy recommend checking out “Arrow Pushing in Organic Chemistry” by Daniel ). Useful in discussions of radical chemistry mechanisms in particular. This is used to show reactions that don’t work: fluorine is a bad leaving in nucleophilic substitutions, for example. The open arrow here doesn’t actually show a “reaction”, per se, but instead more of a mental exercise. Like this: There’s a lot of different ways to go about learning how to do synthesis – and I’ll have a lot more to say about that in future posts – but today’s post addresses one of the simplest and most effective ways of learning how to do it. Maps are easy to understand – they make distances and relationships concrete. Imagine you’re in Laredo, and you want to go to Dallas. You can build reaction maps for other functional s. The more reactions you learn, you’ll see that some types of functional s (like ketones) are very “busy” – like central hubs, there’s lots of reactions that link to them (and link from them). Once you know what reactions to use, it’s much easier to desn your synthesis.
