I (L; R = R1 = Me, R2 = H; R = R2 = H, R1 = Ph; R = H, R1 = Me, R2 = Ph), readily accessible on a large scale from com. available amino alcs., were reacted with M(CH2Ph)4 (M = Zr, Hf) to prepare [L2M(CH2Ph)2] (II). The x-ray crystal structure of [L2Zr(CH2Ph)2] (R = R1 = Me, R2 = H) was determined and showed a cis arrangement for the benzyl ligands. Protonolysis of 3 of II with HNR3BPh4 gave cationic [ML2(CH2Ph)(THF)]BPh4; 2 of these were also prepared via an oxidative pathway utilizing Cp2FeBPh4. The x-ray crystal structure of [HfL2(CH2Ph)(THF)]BPh4 (R = R1 = Me, R2 = H) was obtained and showed a THF mol. cis to the benzyl ligand. A preliminary study of ethylene polymerization with [ZrL2(CH2Ph)(THF)]BPh4 (R = R1 = Me, R2 = H) in toluene showed an interesting, although low, activity. This study involved multiple reactions and reactants, such as 2-(4,4-Dimethyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-91-1Product Details of 163165-91-1).
2-(4,4-Dimethyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-91-1) belongs to oxazolidine derivatives. Oxazolidines are well known as key portions of bioactive molecules or precursors of chiral molecules, as well as established chiral auxiliaries. Oxazolidines are cyclic condensation products of β-amino alcohols and aldehydes or ketone, and they undergo a facile and complete hydrolysis in aqueous solution. Alterations in carbonyl moiety control the rate of formation of a given β-amino alcohol.Product Details of 163165-91-1
