Hexa-1,5-diyn-3-ol ethers as tetramethynyl synthons in cobalt-catalysed acetylene co-oligomerisations; a one-step synthesis of 2,3,6,7-tetrakistrimethylsilylnaphthalene
Abstract
Reaction of hexa-1,5-diyn-3-ol ether derivatives with bistrimethylsilylacetylene in the presence of catalytic amounts of [CpCo(CO)2](Cp = cyclopentadienyl) gives 2,3,6,7-tetrakistrimethylsily Inaphthalene.
