Hydroboration and Oxymercuration of Alkynes
Alkyne chemistry bears many resemblances to alkene chemistry, but in these first few posts on the subject, the purpose is to illustrate how one seemingly

Alkyne Addition Reactions – The “Concerted” Pathway
How does the chemistry of alkynes compare to alkenes? As we’ve seen in some previous posts, there are some significant differences, but a lot of
Read moreHydroboration of Alkenes
So far in this series on alkenes, we’ve gone through two families of mechanism pathways. In the carbocation pathway, we saw reactions that proceed with
Read moreHydroboration of Alkenes: The Mechanism
In the last post we saw that the results of hydroboration of alkenes are not in accord with any of the two families of mechanisms
Read moreAlkene Addition Pattern #3: The “Concerted” Pathway
In contrast to alkene addition reactions in the Carbocation Pathway and the 3-Membered Ring Pathway, we saw in the last two posts that hydroboration of

In this post we’ll do a final review of alkene addition reactions and sum up the three major pathways (and two minor classes of reactions

In a blatant plug for the Reagent Guide, each Friday I profile a different reagent that is commonly encountered in Org 1/ Org 2. Today’s reagent

One of the common complaints you hear a lot from people learning English is that there are just so many exceptions. The plural of “goose”
