TL;DR: Perhydro-1,3-benzoxazines derived from (−)-8-amino menthol behave as masked aldehydes and chiral templates in diastereoselective intramolecular Pauson-Khand reactions with norbornene and norbornadiene.

TL;DR: In this article, a novel silicone and silicon carbide copolymer prepared by copolyming a cyclic or polycyclic non-conjugated diene with polysiloxane or dihydrosilyl hydrocarbon through the so-called hydrosilation was described.

TL;DR: In this paper, a mini-review is devoted to the polymerization of tricyclo [4.2.1.5]non-7-enes (tricyclononenes), which is a product of norbornadiene photo-isomerization.
Abstract: The expansion of the range of available and reactive monomers allowing preparation of novel polymeric materials, is an actual task of polymer chemistry. This mini-review is devoted to the polymerization of tricyclo [4.2.1.02,5]non-7-enes (tricyclononenes) and tricyclo[4.2.1.02,5]nona-3,7-dienes (tricyclonona-dienes)–norbornene type monomers containing norbornene and cyclobutane or cyclobutene fragments in the molecules. Their synthesis is carried out using available cyclopentadiene or quadricyclane, which is a product of norbornadiene photo-isomerization. The features of ring-opening metathesis and addition polymerization of tricyclononenes with participation of double bond in the norbornene fragment are highlighted. Examples of the polymerization of a wide range of tricyclononenes with F-, Si-, O-, and N-containing substituents have demonstrated that they are noticeably more active monomers than norbornenes with the same substituents. The main successes have been achieved in the synthesis of F- and Si-substituted polytricyclononenes, which are promising materials for lithography and membrane gas separation.

TL;DR: In this paper, the skeleton of a cyclotriphosphane unit and the triangle defined by two phosphorus atoms and the metal atom enclose a dihedral angle of 44.8" and 43.4", respectively.
Abstract: Ab s t r a c t. The transition metal-substituted cyclotriphosphane [(qS-C5Me5) (CO)2Fe-P]3 reacts with (norbornadiene)M(CO), (M = Cr, Mo) to give monomeric complexes of the composition q2-[($-C5Me5) (CO) zFe-P]3M(C0)4. The molecular structure of 2 is elucidated by X-ray analysis. The skeleton of the molecule consits of a P3 triangle with one trans and two cis-located Fe(C0)2(C5Me5) substituents. Both cis-configurated phosphorus atoms of the triangle are coordinated to a Cr(CO), :ragment. The bond distance between the two cis orientated phosphorus atoms [2.191(5) and 2.18?(6) A] is slightly shorter with respect to the other P-P bonds [2.206(5), 2.217(5) and 2.214(5), 2.21 l(5) A, respectively]. The cyclotriphosphane unit and the triangle defined by two phosphorus atoms and the metal atom enclose a dihedral angle of 44.8" and 43.4", respectively. The Cr(C0)4 group is severely distorted by interactions with the cis-oriented (q5-C5Mes) (CO)2Fe substituent at P(3).
