The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol( cas:35836-73-8 ) is researched.Reference of 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol.Satoh, Toshifumi; Kinugawa, Yuki; Tamaki, Masaki; Kitajyo, Yoshikazu; Sakai, Ryosuke; Kakuchi, Toyoji published the article 《Synthesis, Structure, and Characteristics of Hyperbranched Polyterpene Alcohols》 about this compound( cas:35836-73-8 ) in Macromolecules (Washington, DC, United States). Keywords: citronellol oxide cationic ring opening polymerization hyperbranched polyterpene alc; nopol epoxide cationic ring opening polymerization hyperbranched polyterpene alc. Let’s learn more about this compound (cas:35836-73-8).
A novel series of bio-based hyperbranched polymers, i.e., hyperbranched polyterpene alcs., were prepared by the cationic ring-opening polymerizations of citronellol oxide (1) and nopol epoxide (2) using boron trifluoride di-Et etherate (BF3·OEt2) as the catalyst. The polymerizations of 1 and 2 homogeneously proceeded without gelation to produce organic solvent-soluble polymers (poly-1 and poly-2, resp.). The absolute weight-average mol. weights (Mw,MALLS), which were measured by a multiangle laser light scattering instrument (MALLS), were 3700-6200 g mol-1 for poly-1 and 9000-20 000 g mol-1 for poly-2, which were ca. 1.4-4.8 times greater than the relative mol. weights (Mw,SEC) measured by size exclusion chromatog. (SEC). The intrinsic viscosities ([η]) of these polymers were very low in the range of 8.5-10.1 mL g-1 for poly-1 and 5.9-9.5 mL g-1 for poly-2. The Mark-Houwink-Sakurada exponent α was calculated to be 0.32-0.40 for poly-1 and 0.25-0.35 for poly-2. These results of the MALLS, SEC, and viscosity measurements suggested that these polymers exist in a compact spherical conformation in solution
