Indlela yokusabela

Hydrazone Bond Formation

I-ADH isabela kunye ne-ketone okanye amaqela e-aldehyde ukwenza iibhondi ze-hydrazone ngokusabela kwe-condensation, ebonakala ngoku:

  1. Ukususwa kwamanzi njengeproduct.
  2. Ukwenziwa konxibelelwano oluzinzileyo lwe-covalent.

Umzekelo wokuphendula:

 

Le ndlela yokusabela ibalulekile ekudaleni izinto ezinokuxhathisa okuphezulu kumatshini, i-thermal, kunye noxinzelelo lokusingqongileyo.

Izinto eziluncedo zokusebenzisa i-ADH
