应用
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.

备注
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.
