资源简介：
A series of monomeric amide or aryloxide complexes of the form LCaX, where L = CH[CMeNC6H3-2,6-
]2,
CH[CMeNC6H4-2-OMe]2, a bulky tris-pyrazolyl borate, TpiPr or TptBu or 9-BBN-pz2 and X = N(SiMe3)2 or OC6H3-2,6-
, has been prepared and characterized and investigated in the ring-opening polymerizations of lactide. The
compounds (TptBu)CaX in THF are shown to be highly active and stereoselective. The propylene oxide complex
(TptBu)Ca(OC6H3-2,6-
)·(PO) has been isolated and structurally characterized (single-crystal X-ray) and shown to
be inert to the polymerization of PO.
