is this my guest today, doctor of chemistry, head of the laboratory of the element of organic compounds russian academy of sciences dmitry sergeevich perekalin sergeevich hello and thank you very much for taking the time to come to the studio. hello dmitry sergeevich a-a click chemistry, but first the simplest question - is this a universal thing or is it something very special in a particular situation, which for some reason has become a working tool in a number of areas of chemical reactions, i don’t know, millions billions an incalculable number, and for some reason, attention, uh, was attracted to a set of chemical reactions that is not so big and everyone is so happy that it is awarded the nobel prize. uh, click chemistry is, shall we say , a very reliable, working reaction. that is to say , when sharpe's bare of the mean proposed this idea to there, er, many at his institute. they were twiddling their thumbs at the temple. so they were saying something like they just said that there are already quite a lot of chemical reactions. what else does he need. ah, but the idea is that the idea of ​​click chemistry i
