Having gone through the E1 mechanism for elimination reactions, we’ve
accounted for one way in which elimination reactions can occur.
However, there’s still another set of data that describes some
elimination reactions that we haven’t adequately explained yet. Here’s
an example of the reaction I’m talking about: What’s interesting about
this reaction is that it [...]

Treatment of alcohols with thionyl chloride (SOCl2) converts alcohols
to alkyl chlorides. When the reaction is performed on secondary
alcohols with a stereocenter, the reaction proceeds with inversion of
configuration. Related Posts:Introducing the Reaction GuideOrganic

In a blatant plug for the Reagent Guide and the Reagents App for
iPhone, each Friday I profile a different reagent that is commonly
encountered in Org 1/ Org 2. What it’s used for: For our purposes, zinc
amalgam has one important use: in the Clemmensen reduction of ketones
to alkanes. Similar to: The reagent has essentially the same [...]

In a blatant plug for the Reagent Guide and the Reagents App for
iPhone, each Friday I profile a different reagent that is commonly
encountered in Org 1/ Org 2. If there’s one thing you learn how to do
well in Org 1, it’s make alcohols. Let’s count the ways: hydroboration,
acid-catalyzed hydration, oxymercuration for starters, and then
substitution [...]

In a blatant plug for the Reagent Guide and the Reagents App for
iPhone, each Friday I profile a different reagent that is commonly
encountered in Org 1/ Org 2. It’s almost been 100 years since Paul
Sabatier was awarded the 1912 Nobel prize for his discovery that
hydrogen gas will add to alkenes (among other molecules, such as [...]

In a blatant plug for the Reagent Guide and the Reagents App for
iPhone, each Friday I profile a different reagent that is commonly
encountered in Org 1/ Org 2. Today’s reagent is probably a bit on the
obscure side, but it solves a useful problem. Lithium tri tert-butoxy
aluminum hydride is lot like lithium aluminum hydride, but with [...]

In a blatant plug for the Reagent Guide and the Reagents App for
iPhone, each Friday I profile a different reagent that is commonly
encountered in Org 1/ Org 2. One of the things about learning organic
chemistry from a textbook is that about 98% of you will never really
have to consider the practical aspects of working with [...]

In a blatant plug for the Reagent Guide and the Reagents App for
iPhone, each Friday I profile a different reagent that is commonly
encountered in Org 1/ Org 2. Sometime back in general chemistry you
(hopefully) learned that hydroxide ion (HO-) is a strong base. It’s the
conjugate base of water – that is to say, that’s what’s [...]

In a blatant plug for the Reagent Guide and the Reagents App for
iPhone, each Friday I profile a different reagent that is commonly
encountered in Org 1/ Org 2. In organic chemistry, sometimes you need
to build molecules up. Other times, you need to break molecules down.
Ozone, which we talked about earlier, is a really useful reagent [...]

wouldn’t be free forever. Today’s the last day to pick up the Reagents
app for free from the App Store! Get it [...]
