摘要:
AbstractStereochemical studies, made possible by asymmetric labeling with hydrogen isotopes, have led to the hypothesis that enzymic association of C5units in polysoprenoid synthesis is not a concerted process but proceeds in two steps: a trans 1,2‐addition to an olefin followed by a trans 1,2‐elimination. It is shown that similar mechanisms can also explain the cyclization of squalene epoxide to tetracyclic and pentacyclic triterpeno

摘要:
AbstractSimultaneous as well as successive polymerization and crystallization is possible. While crystallization after polymerization usually produces folded chain lamellar crystals, crystallzation during polymerization frequently produces fibrillar extended chain crystals.

摘要:
AbstractReaction of potassium phthalimide with halogenoalkanes and with a variety of other alkylating agents leads to the N‐alkylphthalimide. N‐Substituted phthalimides may be converted into the corresponding primary amine by hydrolysis or hydrazinolysis. The scope and limitations of these reactions, which together constitute the Gabriel Synthesis of primary amines, are revie

摘要:
AbstractKinetic studies of substitution reactions of carbonylmetals and of carbonylmetal derivatives in which other ligands (n or π donors) besides CO are bound to the metal atom have recently attracted great interest, and the results of these investigations throw a new light on theoretical and preparative problems. The substitution mechanism is determined mainly by steric and electronic factors
