This paper explores the copolymerization of l-lactide (l-LA) with 2,2-[2-pentene-1,5-diyl]trimethylene
carbonate ( c HTC). Since c HTC has a cyclohexene group, this provided a route for …

… An outcome of this study was determining that the ZnEt 2 −H 2 O (1/0.5) catalyst for a
monomer/catalyst (M/C) molar ratio of 400 and a 2 h reaction time gave a product with M n = 276 …

… (2-alkenyl-3-pentene-1,5-diyl)iron complexes can serve as organometallic scaffolds for the
preparation of a wide variety of structural motifs containing up to 5 contiguous stereocenters. …
