Zinc anilido-oxazolinate complexes as initiators for ring opening polymerization.
Three new anilido-oxazolines, ortho-C(6)H(4)(NHAr')(4,4-dimethyl-2-oxazoline) [Ar'=2,4,6-trimethylphenyl, HNPh(TriMe)Oxa (1); 2,6-diisopropylphenyl, HNPh(DiiPr)Oxa (2); 2-methoxyphenyl, HNPh(OMe)Oxa (3)], have been prepared. Reactions of 1 or 2 with one molar equivalent of ZnEt(2) in tetrahydrofuran or hexane solution give the zinc ethyl complexes (NPh(TriMe)Oxa)ZnEt (4) and (NPh(DiiPr)Oxa)ZnEt...
متن کاملNi(II) tetraphosphine complexes as catalysts/initiators in the ring opening polymerization of ε-caprolactone.
Reactions of the tetraphosphine ligand N,N,N',N'-tetra(diphenylphosphanylmethyl)ethylene diamine) (dppeda) or 1,4-N,N,N',N'-tetra(diphenylphosphanylmethyl)benzene diamine (dpppda) with NiCl2, ancillary ligand (C2H5)2NCS2Na (Na(dtc)) and NH4PF6 afforded two binuclear complexes [(dtc)Ni(dppeda)Ni(dtc)](PF6)2 (1) and [(dtc)Ni(dpppda)Ni(dtc)](PF6)2 (2). Compounds 1 and 2 were characterized by eleme...
متن کاملTritylium ions as initiators and co-initiators in cationic polymerizations
On the other hand, the less stabilized tris(4chlorophenyl)methyl cation (1 b) was reported to initiate the polymerization of isobutene3). In accordance, p-methoxy and p-methyl substituted tritylium ions do not initiate the polymerization of a-methylstyrene, in contrast to the less stable 1 a and 1 b4). Only for few reactive monomers, however, the initiation was proven to proceed via addition of...
متن کاملChiral indium alkoxide complexes as initiators for the stereoselective ring-opening polymerization of rac-lactide.
The indium complex InL(2)N'' has been prepared from the reaction of 2 equiv of ((t)Bu)(2)P(O)CH(2)CH((t)Bu)OH (HL) with InN''(3) (N'' = N(SiMe(3))(2)). This complex reacts with a further equivalent of 2,6-di-tert-butylphenol or HL to afford the adducts InL(2)(OAr) and InL(3), respectively. Confirmation that the anion L(-) exhibits "ligand self-recognition" in the formation of predominantly homo...
متن کاملMathematics with DERIVE as Didactical Tool
In this talk, I would like to show you how DERIVE can be used as a didactical tool in secondary high school education. For my demonstration I use the newest release DERIVE for Windows 5 which supports the use of worksheets. I will concentrate on some examples describing general topics that I find most appropriate to enhance our educational opportunities. In this introduction, I would like to em...
