摘要:Metal salts of saturated aliphatic alcohols can be used as modifiers in lithium initiated solution polymerizations of diene monomers into rubbery polymers. Sodium t-amylate is a preferred modifiers because of its exceptional solubility in non-polar aliphatic hydrocarbon solvents that are employed as the medium for such solution polymerizations. However, using sodium t-amylate as the polymerization modifier in commercial operations where recycle is required can lead to certain problems. These problems arise due to the fact that sodium t-amylate reacts with water to form t-amyl alcohol during steam stripping in the polymer finishing step. Since t-amyl alcohol forms an azeotrope with hexane, it co-distills with hexane and thus contaminates the feed stream. The present invention solves the problem of recycle stream contamination. This invention is based upon the discovery of highly effective modifiers that do not co-distill with hexane or-form-compounds during steam stripping which co-distill with hexane. The modifiers of this invention are metal salts of cyclic alcohols. Since the boiling points of these metal salts of cyclic alcohols are very high, they do not co-distill with hexane and contaminate recycle streams. Additionally, metal salts of cyclic alcohols are considered to be environmentally safe. The, subject invention more specifically discloses an initiator system which is comprised of (a) a lithium initiator, (b) a metal salt of a cyclic alcohol, and (c) a polar modifier.

摘要:Metal salts of cyclic alcohols can be used as modifiers in lithium initiated solution polymerizations of diene monomers into rubbery polymers having a low vinyl content. For instance, such initiator systems can be used in the copolymerization of styrene and isoprene to produce low vinyl styrene-isoprene rubber having a random distribution of repeat units that are derived from styrene. It is important for such polymerizations to be conducted in the absence of polar modifiers, such as Lewis bases. The subject invention more specifically discloses an initiator system which is comprised of (a) a lithium initiator and (b) a metal salt of a cyclic alcohol, wherein said initiator system is void of polar modifiers. The present invention also discloses a process for preparing a rubbery polymer having a low vinyl content which comprises: polymerizing at least one diene monomer with a lithium initiator at a temperature which is within the range of about 5° C. to about 100° C. in the presence of a metal salt of a cyclic alcohol, wherein the molar ratio of the metal salt of the cyclic alcohol to the lithium initiator is within the range of about 0.05:1 to about 10:1, and wherein the process is conducted in the absence of polar modifiers.

标题 :Synthesis of 4-(pentafluorosulfanyl)benzenediazonium tetrafluoroborate and analogs

摘要:4-(pentafluorosulfanyl)benzenediazonium tetrafluoroborate salt was synthesized and isolated. The pentafluorosulfanyl salt was examined in a wide assortment of reactions to form novel SF 5 -bearing alkenes, alkynes, and biaryl derivatives using Heck-Matsuda, Sonogashira, and Suzuki coupling protocols. Dediazoniation of the salt furnished the corresponding p-SF 5 —C 6 H 4 X, C 6 H 4 OS(O)(CF 3 )â•?NSO 2 CF 3 , and p-SF 5 —C 6 H 4 —NTf 2 derivatives. The azide derivative p-SF 5 —C 6 H 4 N 3 entered into click chemistry with phenylacetylenes to furnish the corresponding triazoles. Various SF 5 -bearing alkenes were synthesized by coupling reactions using a metal catalyst. Fluorodediazoniation selectively furnished the fluoro derivative p-SF 5 —C 6 H 4 F. Homolytic dediazoniation gave the unsymmetrical biaryls, thus demonstrating the broad utility of pentafluorosulfanyl diazonium salts as building blocks of SF5-aromatics that are in high demand in many branches of chemistry including biomedicine and materials chemistry.
