Uses

Used in Inorganic Chemistry:
1,7-Octadiyne is used as a chain extension unit for the formation of uranium(IV) vinyl complexes, which are important in the study and development of new inorganic compounds and materials.
Used in Organic Chemistry:
1,7-Octadiyne is used as a reactant in the reaction with frustrated Lewis pairs, such as P(o-tolyl)3/B(C6F5)3, where it undergoes acetylene C-C coupling to yield zwitterionic products. This application is significant in the exploration of new reaction mechanisms and the synthesis of novel organic compounds.
Used in Coordination Chemistry:
1,7-Octadiyne is used in the reductive cyclization reaction with Re2Cl4(μ-dppm)2 (dppm = Ph2PCH2PPh2), leading to the formation of quadruply bonded dirhenium(III) complex Re2Cl3(μ,η2-C8H7)(μ-dppm)2. This application is valuable in the field of coordination chemistry for the synthesis of complexes with unique bonding characteristics and potential applications in catalysis and other areas.

Synthesis of lanthanide(II)-imine complexes and their use in carbon-carbon and carbon-nitrogen unsaturated bond transformation

Ytterbium and samarium metals reduced aromatic ketimines to give directly divalent azalanthanacyclopropane complexes 1 quantitatively, the structure of which was characterized by X-ray analysis. The imine complexes 1 catalyzed dehydrogenative silylation of terminal alkynes, hydrosilylation of imines and alkenes, and intermolecular hydrophosphination of alkynes. Moreover, dehydrogenative double silylation of conjugated dienes was achieved with 1.

Cyclic Diynes by Alkyne Metathesis

The preparation of α,ω-diynes with methyl groups at the termini (11a-i) is described. The methylene groups between the alkyne units vary between n = 12 (a) and n = 4 (i). Ring closing metathesis with Mo(CO) 6/CF3C6H4OH yielded the monocyclic alkyne 12a with 11a as starting material, whereas 11b-g yielded the cyclic diynes 13b-g. Detailed structural parameters were obtained for 13b and 13c by X-ray crystallography.

Dehydrogenative silylation of terminal alkynes catalyzed by Ytterbium- imine complexes

Catalytic dehydrogenative silylation of terminal alkynes with hydrosilanes has been achieved by using divalent Yb-imine complexes. The reaction with mono-, di-, and trihydrosilanes gave the corresponding alkynylsilanes in good yields. α,ω-Diynes were similarly silylated at both termini. Thus, oligomers were obtained from the diynes and dihydrosilanes. In addition, it has been found that the imine complexes exhibit catalytic activity for redistribution of the silyl groups of the alkynylsilanes and for Si-Si bond fission of disilanes.
