Katalitska C-H aktivacija s 3d prehodnimi kovinami

diplomsko delo

Pia Podobnik (Author), Franc Požgan (Mentor)

Abstract

V zadnjih letih prihaja na področju organske sinteze do intenzivnega razvoja reakcij C−H aktivacije, saj ne potrebujejo predfunkcionalizacije, ker poteče direktna prekinitev nereaktivne C−H vezi, kar zmanjša število reakcijskih stopenj in preprečuje nastanek velikega števila stranskih produktov. Reakcije za katalizatorje večinoma uporabljajo plemenite 4d in 5d prehodne kovine zaradi njihovih dobrih katalitskih lastnosti. Med reakcijami C−H aktivacije pa je pozornost vedno bolj usmerjena proti okolju prijaznejšim reakcijam, kataliziranim s 3d prehodnimi kovinami. Te so namreč v primerjavi s plemenitimi kovinami manj strupene, lažje dostopne in cenejše. V svojem diplomskem delu bom najprej v uvodu povzela tradicionalne reakcije križnega spajanja in splošno predstavila C−H aktivacijo. V nadaljevanju bom predstavila vsako 3d prehodno kovino posebej in opisala kako katalizira eno reakcijo tvorbe C−C in eno reakcijo tvorbe C−Het vezi.

Secondary title:	Catalytic C-H activation with 3d transition metals
Secondary abstract:	In recent years, there has been an intensive development of C−H activation reactions in the field of organic synthesis, as they do not require pre-functionalization, because direct cleavage of unreactive C−H bond takes place, which reduces the number of reaction steps and prevents the formation of a large number of side products. Reactions mostly use noble 4d and 5d transition metals for catalysts because of their good catalytic properties. Among C−H activation reactions, attention is increasingly directed towards more environmentally friendly reactions, catalyzed by 3d transition metals. Compared to precious metals, these are less toxic, easier to access and cheaper. In my thesis, I will first summarize the traditional cross-coupling reactions in the introduction and give a general presentation of C−H activation. Then, I will present each 3d transition metal separately and describe how it catalyzes one C−C bond formation reaction and one C−Het bond formation reaction.
