Huang, Tzu-Lun published the artcileCalcium complexes containing oxalamidinate ligands as catalysts for ¦Å-caprolactone polymerization, Recommanded Product: 2-(Methylthio)ethanamine hydrochloride, the publication is Dalton Transactions (2013), 42(25), 9255-9262, database is CAplus and MEDLINE.
A series of calcium complexes containing oxalamidinate ligands is described. Reactions of oxalamidinate ligand precursors, [PhN:C{NH(CH2)2OMe}-C{NH(CH2)2OMe}:NPh] (1), [PhN:C{NH(CH2)2NMe2}-C{NH(CH2)2NMe2}:NPh] (2), [PhTriMeN:C{NH(CH2)2OMe}-C{NH(CH2)2OMe}:NPhTriMe] (3), [PhTriMeN:C{NH(CH2)2SMe}-C{NH(CH2)2SMe}:NPhTriMe] (4), [PhTriMeN:C{NHCH2Py}-C{NHCH2Py}:NPhTriMe] (5), with two molar equivalents of Ca[N(SiMe3)2]2(THF)2 gave calcium oxalamidinate complexes, [Ca{N(SiMe3)2}(THF)(PhN)C{N(CH2)2OMe}-]2 (6), [Ca{N(SiMe3)2}(THF)(PhN)C{N(CH2)2NMe2}-]2 (7), [Ca{N(SiMe3)2}(THF)(PhTriMeN)C{N(CH2)2OMe}-]2 (8), [Ca{N(SiMe3)2}(THF)(PhTriMeN)C{N(CH2)2SMe}-]2 (9), [Ca{N(SiMe3)2}(THF)(PhTriMeN)C{NCH2Py}-]2 (10), resp. The mol. structure of complex 7 was further characterized by the single crystal x-ray diffraction technique. The catalytic activities of complexes 6-10 toward the ring opening polymerization of ¦Å-caprolactone were studied. Complex 8 exhibited excellent activity for the polymerization of ¦Å-caprolactone with controlled mol. weights and polydispersities.
