4.Qaab dhismeedka kiimikaadku waxa uu ka kooban yahay atom boron ah oo ku xidhan koox phenolic ah iyada oo loo sii marayo isku xidhka ester-ka, taas oo ka dhigaysa dhisme qiimo leh oo loogu talagalay isku-dhafka dabiiciga ah. - falcelinta isku-xirnaanta.Dareen-celintani waxay ku lug leedahay samaynta isku xidhka kaarboon-carbon ee u dhexeeya aryl ama vinyl boronic acid iyo aryl ama vinyl halide ama triflate.Sida ester boronic ah, HBP ester wuxuu u dhaqmaa sidii horudhac u ah boron acid-ka u dhigma, kaas oo mari kara falcelinta isku-dhafka ah ee electrophiles kala duwan, taasoo horseedaysa samaynta unugyo dabiici ah oo adag.Dareen-celintani waxay leedahay codsiyo muhiim ah oo ku saabsan kimistariga daawada, isku-darka agrochemical, sayniska maadada, iyo meelo kale oo badan oo ka mid ah synthesis organic. The versatility of HBP ester been in ay awood u leh inay maraan isbedel kooxeed functional, sida oksaydhka ama dhimista, si ay u soo bandhigto hawl dheeraad ah galay molecule.Tusaale ahaan, kooxda hydroxyl ee moiety phenolic waa la ilaalin karaa ka dibna waa la ilaalin karaa, taas oo u oggolaanaysa beddelka xulashada iyo kala-duwanaanta xarunta.Hantidani waxay ka dhigaysa HBP ester qalab qiimo leh oo ku jira isku-darka daawooyinka, agrochemicals, iyo kiimikooyinka kale ee wanaagsan. Intaa waxaa dheer, HBP ester waxaa badanaa loo isticmaalaa dhismaha dareemayaasha molecular iyo baarayaasha.Atamka boron-ka ee qaab-dhismeedkiisa awgeed, waxa uu samayn karaa dhismayaal la beddeli karo oo leh diols ama polyols, sida sonkor ama karbohaydraytyo.Hantidani waxay awood u siinaysaa horumarinta dareemayaasha ku salaysan boronate si loo ogaado gulukooska, iyo sidoo kale unugyo kale oo bayooloji ah.HBP ester waxaa lagu dhex dari karaa meelo kala duwan oo dareenka ah, oo ay ku jiraan fluorescent ama midabada midabaynta, siinta hab lagu ogaanayo falanqaynta gaarka ah ee shaybaarada bayoolojiga ama deegaanka. Marka laga reebo isticmaalka qalabka dabiiciga ah iyo codsiyada dareenka, 4-Hydroxyphenylboronic acid pinacol ester ayaa sidoo kale la baaray. doorka suurtagalka ah ee ay ku leedahay hababka bixinta daroogada.Atomka boron wuxuu ka qaybqaadan karaa isdhexgalka biomolecules, sida asiidhyada nucleic ama borotiinka, waxaana lagu sahamiyay gaarsiinta daawada lala beegsaday, kor u qaadista qaadashada gacanta, ama la xakameeyey sii deynta wakiilada daweynta. loo isticmaalo isku-dhafka organic, codsiyada dareenka, iyo hababka gudbinta daroogada.Shaqadeeda ester boronic waxay awood u siinaysaa inay ka qayb qaadato falcelinta isku-xidhka Suzuki-Miyaura oo ay marto isbeddello kooxeed oo shaqaynaysa, iyada oo balaadhisa adeegeeda synthetic.Intaa waxaa dheer, HBP ester waxay samayn kartaa dhismo dib loo rogi karo oo leh diols, taasoo ka dhigaysa mid qiimo leh horumarinta dareemayaasha unugyada.Awooddeeda hababka gudbinta daroogada ayaa sii hoosta ka xariiqaysa muhiimada ay leedahay inay tahay xarun la taaban karo oo ku saabsan dhinacyada sayniska iyo tignoolajiyada ee kala duwan.
