Superior conditions for the isomerisation of (–)-humulone into (+)-cis- and (–)-trans-isohumulone are described, together with a highly effective separation on Kieselgel H. The isohumulones are fully characterised for the first time, the mechanism of their formation is discussed, and their ...
The energy gap between the acyclic structures of cis- and trans-1,3-tetragermabutadiene 3 and the minimum is significantly reduced and is expected to reverse with even bulkier groups and therefore corresponds well with the experimental results. At the level of theory used herein, no bond ...
Polymerization methods that control the cis/trans stereochemistry of repeating alkenes in polyalkenamers remain scarce. Now, an acyclic diene metathesis process has been developed that enables control over the stereochemistry of the polymer backbone. The method harnesses the reactivity of dithiolate Ru ca...
An improved synthesis of the known compound [(PMe2Ph)2(PtB10H12)] has been developed by deprotonation of B10H14 with NNN′N′-tetramethylnaphthalene-1,8-diamine followed by treatment with cis-[PtCl2(PMe2Ph)2]. This reaction has been applied to the 2,2′, 2,6′, and 1,5′ isomers...

The solid-phase chemistry literature from the 1960s to 1997 has been reviewed with an emphasis on organic chemistry. Reactions have been classified according to the products formed on the solid phase, the types of chemistry performed, names of chemical reactions, asymmetric reactions and transition ...
