An air stable moisture resistant titanium triflate complex as a lewis acid catalyst for C-C bond forming reactions was written by Bull, Steven D.;Davidson, Matthew G.;Johnson, Andrew L.;Mahon, Mary F.;Robinson, Diane E. J. E.. And the article was included in Chemistry – An Asian Journal in 2010.Safety of 3-Acryloyloxazolidin-2-one This article mentions the following:
An air and moisture stable C3-sym. titanium(IV) triflate, supported by a tripodal amine-(tris-phenolate) ligand, has been synthesized and characterized by x-ray crystallog. and shown to be a good Lewis acid catalyst for a range of aza-Diels-Alder, Diels-Alder, syn aldol, allylation, and alkylation reactions. In the experiment, the researchers used many compounds, for example, 3-Acryloyloxazolidin-2-one (cas: 2043-21-2Safety of 3-Acryloyloxazolidin-2-one).
3-Acryloyloxazolidin-2-one (cas: 2043-21-2) belongs to oxazolidine derivatives. Oxazolidines are commonly obtained by reaction of strained heterocycles, mainly aziridines. 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. Oxazolidines are weaker bases (pKa 6–7) than parent β-amino alcohols and found to be more lipophilic than the parent compound at physiological pH.Safety of 3-Acryloyloxazolidin-2-one
