Abstract
Aldehdi, ketoni te derivati karboksilnih kiselina su spojevi koji sudjeluju u različitim kemijskim reakcijama. Djelomična polarizacija veze ugljik - kisik u karbonilnoj skupini doprinosi jačanju elektrofilnog karaktera karbonilnog ugljikova atoma. Mnogi biološki važni spojevi esencijalni za normalno funkcioniranje organizma sintetiziraju se mehanizmima nukleofilne supstitucije, adicije te kondenzacije u kojima nastaje nova C–C veza. U reakcijama s organometalnim reagensima ugljikov atom zbog polarizacije veze dobiva nukleofilni karakter zbog čega ima sposobnost nukleofilnog napada na elektrofilne karbonilne spojeve i derivate karboskilnih kiselina pri čemu dolazi do nastanka alkohola. U α - kondenzacijskim reakcijama, pojavljuje se novo reakcijsko središte ili α – ugljikov atom koji se također ponaša kao nukleofil. U reakcijama kondenzacije dolazi do sinteze α, β – nezasićenih spojeva koji se daljnim reakcijama mogu polimerizirati u veće molekule. U svim navedenim reakcijskim mehanizmima dolazi do formiranja najmanje jedne C – C veze što u kemijskom i biološkom pogledu ima poseban značaj.
Abstract (english)
Aldehydes, ketones and carboxylic acids derivatives are compounds which take part in various chemical reactions. Partial polarization of carbon-oxygen bond in carbonyl group contributes in strengthening the electrophilic character of the carbonyl carbon atom. Many important biological compounds essential for normal functioning of the organism are being synthethized using mechanisms such as nucleophilic substitution, addition and condensation. In reactions with organometallic reagents due to the bond polarization, the carbon atom becomes nucleophilic and has the ability to attack electrophilic carbonyl compounds and derivatives of carboxylic acids and create alcohols. In α-condensation reactions there is a new reaction centre or α-carbon atom that has a nucleophilic character. In condensation reactions α,β-unsaturated compounds are being formed that could be subsequently polymerized in larger molecules with additional reactions. In all reaction mechanisms listed above at least one C-C bond is created that has a significant meaning in biological and chemical reactions.
