All reactions proceed via an initial addition of the radical to alkenes, alkynes and aromatic species.
Alternatively, acetylene may yield amino acids directly via a conversion of an alkyne to the corresponding aldehyde, which then forms an alpha amino nitrile and eventually an amino acid.
Additionally, this compound can by produced through the hydration of an alkyne through mecuric sulfate catalysis.
Using a protected alkyne, as opposed to acetylene gas, prevents further (undesired) coupling reactions and also has the benefit of being a liquid.
The four main categories are (1) nucleophilic attack on an alkene alkyne, or allyl ligand and (2) insertion of the alkene into the metal-amide bond.
Usually, the substrate is an alkene or an alkyne.
The reaction shown below involves an alkyne oxymercuration reaction to generate the requisite ketone.
In the first step of this reaction, a metal acetylide is formed by reaction of the terminal alkyne with the copper salt.
Managing Your Emotions
What makes me angry?
Какво ме ядосва?
Mostly，l hate when someone tries to make someone else feel bad.
Най-вече мразя, когато някой се опитва да накара някой друг да се чувства зле.
I have to admit that once, when l was actually called names.
Трябва да призная, че веднъж, когато наистина ме нарекоха.
l regretted doing this afterwards, but not full heartedly because l think l was provoked in that situation.
След това съжалявах, че го направих, но не искрено, защото смятам, че бях провокиран тази ситуация.
The most postive way of dealing with anger is talking about the problem.
Най-положителният начин за справяне с гнева е да говорите за проблема.
l talk to someone who listens, or l'll write my thoughts down on paper.
Говоря с някой, който ме слуша, или ще напиша мислите си на хартия.
Learning how to deal with anger as you're growing up is so important.
Да се научите как да се справяте с гнева, докато растете, е толкова важно.
When you're younger, you might yell,or cry when you're angry, but as you get older, you're expected to handle your emotions much better.
Когато си по-млад, може да крещиш или да плачеш, когато си ядосан, но когато остарееш, ти си се очаква да се справят с емоциите ви много по-добре.
Learning to control your emotion now will prevent you from doing something that you'll regret later on in life!
Ако се научите да контролирате емоциите си сега, ще ви попречи да направите нещо, което ще направите съжалявам по-късно в живота!
