General description
Gas-phase reaction of the OH radical with 3-methyl-1-butene in the presence of NO has been investigated. Polymerization of 3-methyl-1-butene in the presence of homogeneous metallocene catalyst (co-catalyst methylalumoxane) has been investigated.
Application
3-Methyl-1-butene has been used in asymmetric total synthesis of (−)-Linderol A, a potent inhibitor of melanin biosynthesis of cultured B-16 melanoma cells.
Other Notes
Brass hose adapter Z146811 or brass body mini gas regulator Z513539 is recommended.
