TL;DR: In this paper, the trans-transoid sequence of polyacetylenes with a triphenylamine moiety was shown to be induced by cis-to-trans isomerization.
Abstract: Novel soluble polyacetylenes having a triphenylamine moiety were synthesized by a [Rh(norbornadiene)Cl]2 catalyst under quite mild conditions in fairly high yields. The obtained polymer showed to have trans-transoid sequence as the major main-chain structure which was generated through the so-called cis-to-trans isomerization was already induced even during the polymerization. The HCl doping of the polymer was resulted in the formation of the oxidized polymer where the so-called polaron or bipolaron was produced. In addition, we found that in the case of the pristine polymer unpaired electrons mainly localized on the triphenylamine moiety as the side chain. On the other hand, after the doping the unpaired electron delocalized on the main chain of the polymer.

TL;DR: The interaction of P,N-containing cyclophanes containing two 1,5-diaza-3,7-diphosphacyclooctane fragments with tetracarbonyl(tetrahydrofuran)tungnsten(0) or tetracarbonel(norbornadiene)molybdenum(0,1) was studied in this paper.

TL;DR: In this paper, the ability of methyl esters of 1-alkylcyclopropene-3-carboxylic acids to cyclopropanate norbornadiene or dicyclopentadiene, with the formation in up to 75% yield of the corresponding vinylcyclopropane adducts has been discovered.
Abstract: 1.
The ability of methyl esters of 1-alkylcyclopropene-3-carboxylic acids to cyclopropanate norbornadiene or dicyclopentadiene, in the presence of copper (I) chloride or its complexes, with the formation in up to 75% yield of the corresponding vinylcyclopropane adducts has been discovered. Products were the methyl esters of 3-(tricyclo[3. 2.1.02,4]oct-6-en-3-yl)alk-2-enoic and 3-(tetracyclo[5.3.1.02,608,10]undec-3-en-9-yl)alk-2-enoic acids respectively.
2.
The methyl esters of 1-alkylcyclopropenecarboxylic acids were isomerized, in a medium of cycloocta-1,5-diene, cyclohexene, methylenecyclopropane, or methyl acrylate in the presence of copper (I) chloride or its complexes, into 2-methoxy-4-alkylfuran (yields up to 65%) and partially oligomerized, but with cyclopentadiene the corresponding diene adduct was formed.
3.
A concerted mechanism has been proposed and theoretically substantiated for the formation of vinylcyclopropane derivatives from substituted cyclopropenes and olefins in the coordination sphere of copper without the participation of vinylcarbenes or their complexes.
