General Description

3-Methyl-3-heptene, also known as octene, is a chemical compound with the molecular formula C8H16. It is a colorless liquid with a mild, sweet odor and is commonly used as a precursor in the production of various chemical compounds, including plasticizers, adhesives, and surfactants. 3-Methyl-3-heptene is also used as a solvent in the manufacturing of paints, coatings, and cleaning products. Additionally, it is used as a fuel additive and in the production of pharmaceuticals and agricultural chemicals. It is important to handle this chemical with care as it may cause irritation to the skin, eyes, and respiratory system upon exposure.

DIARYL AMINE ANTIOXIDANTS PREPARED FROM BRANCHED OLEFINS

Diaryl amines are selectively alkylated by reaction with branched olefins, which olefins are capable of forming tertiary carbonium ions and can be conveniently prepared from readily available branched alcohols. The diaryl amine products are effective antioxidants and often comprise a high amount of di-alkylated diaryl amines and a low amount of tri- and tetra-alkylated diaryl amines.

Polylithiumorganic compounds. Part 28. The reaction of allene and alkyl substituted allenes with lithium metal

The reaction of allene (3a) and alkyl substituted allenes 1,2-hexadiene (3b), cyclopropylallene (3c), and vinylidene cyclopropane (3d) with lithium metal was investigated in order to access 2,3-dilithioalkenes 4a-d. These dilithioalkenes 4a-d are very reactive in polar solvents like THF and act as strong bases, either metalation of the starting allene 3a-d, the solvent, or sufficiently acidic intermediates like 8 a-d is observed. The metalation products 5-7 show follow-up reactions like 1,3-H shift to the corresponding 1-lithio-1-alkynes 8 and subsequent metalation to the dilithioalkynes 9. Additionally, lithium hydride elimination and ring-chain rearrangement (for 5c) are observed. 1,2-Hexadiene (3b) can be brought to reaction with lithium metal in the apolar solvent pentane, here the follow-up reactions are much slower due to the insolubility of 4b. In all cases the elucidation of the reaction pathways is hampered by the formation of complex mixtures of, amongst others, regio- and stereoisomeric products upon quenching with simple electrophiles.
