A Quote by Akira Suzuki
Our case, we used the organometallic compounds. Additionally, we need one important element, that is base. Without base, the acidic coupling reaction using organoboron compounds cannot proceed nicely. So, that is very important point in our cross-coupling reaction.

The palladium-catalyzed cross-coupling reaction between different types of organoboron compounds and various organic electrophiles including halides or triflates in the presence of a base provides a powerful and general methodology for the formation of carbon-carbon bonds.
Carbon-carbon bond formation reactions employing organoboron compounds and organic electrophiles have recently been recognized as powerful tools for the construction of new organic compounds.
The coupling of aryl halides with copper at very high temperature is called the Ullmann reaction, which is of broad scope and has been used to prepare many symmetrical biaryls. However, when a mixture of two different aryl halides is used, there are three possible biaryl products.
It is important to have a base in life, and from that base you can enjoy it. To me the base is family.
Direction coupling between the various radiations generated in a nuclear reaction both with one another and with the initiating radiation can also be detected and measured by coincidences; this provides valuable information about the structure of the atomic nuclei.
Happiness and sadness are just two eternal truths like day and night. A man of superior intellect is never affected by these emotions. They are not base emotions at all but a reflection of our thoughts, a reaction to our perspective on things we see, hear and do. Equanimity is not only desirable in a warrior, but a must. Without it, you are as good as dead in the battlefield.
It was very important to my father-in-law that we didn't feel like we deserted our base of voters.
The only difference between elements and compounds consists in the supposed impossibility of proving the so-called elements to be compounds.
The feeling you get from playing to a good audience is hard to describe without sounding as though you are talking silly. But reaction is important. You might feel in yourself that you're doing it ok but it's when you get the live reaction that you know you're doing it right.
Base words are uttered only by the base
And can for such at once be understood;
But noble platitudes - ah, there's a case
Where the most careful scrutiny is needed
To tell a voice that's genuinely good
From one that's base but merely has succeeded.
My favorite food was seafood, and that's all I used to eat. And then there I was, 27 years old, and bam, I have this allergic reaction - and it's life-threatening. So it's very important to spread the word and spread awareness so people can be better prepared in case anaphylaxis occurs in their life.
Few scientists acquainted with the chemistry of biological systems at the molecular level can avoid being inspired. Evolution has produced chemical compounds exquisitely organized to accomplish the most complicated and delicate of tasks. Many organic chemists viewing crystal structures of enzyme systems or nucleic acids and knowing the marvels of specificity of the immune systems must dream of designing and synthesizing simpler organic compounds that imitate working features of these naturally occurring compounds.
As soon as we can wrest from Nature the secret of the internal structure of the compounds produced by her, chemical science can then even surpass Nature by producing compounds as variations of the natural ones, which the living cell is unable to construct.
But, most important, we must not become as base and treacherous as our enemies.
The reaction to any word may be, in an individual, either a mob-reaction or an individual reaction. It is up to the individual to ask himself: Is my reaction individual, or am I merely reacting from my mob-self? When it comes to the so-called obscene words, I should say that hardly one person in a million escapes mob-reaction.
What is needed is a marriage of two impulses, a coupling of the urge to do something positive with the willingness to constantly re-evaluate how effectively our actions lead to our goal - that of ending world hunger.
