Description

CAS: 871-84-1 | C8H10 | 106.17 g/mol

1,7-Octadiyne is an useful bifunctional chain extension unit. It participates in the formation of uranium(IV) vinyl complexes. It reacts with frustrated Lewis pair P(o-tolyl)3/B(C6F5)3 by acetylene C-C coupling to yield the zwitterionic product. It undergoes the reductive cyclization during reaction with Re2Cl4(?-dppm)2 (dppm = Ph2PCH2PPh2) and affords quadruply bonded dirhenium(III) complex Re2Cl3(?,η2-C8H7)(?-dppm)2.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
1,7-Octadiyne is an useful bifunctional chain extension unit. It participates in the formation of uranium(IV) vinyl complexes. It reacts with frustrated Lewis pair P(o-tolyl)3/B(C6F5)3 by acetylene C-C coupling to yield the zwitterionic product. It undergoes the reductive cyclization during reaction with Re2Cl4(μ-dppm)2 (dppm = Ph2PCH2PPh2) and affords quadruply bonded dirhenium(III) complex Re2Cl3(μ,η2-C8H7)(μ-dppm)2.

Solubility
Not miscible or difficult to mix.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature is 2 - 8°C. Incompatible with strong oxidizing agents.
