Abstract:
9,10-Dihydroanthracene-9,10-diyl-bridged B(2)(NMe(2))(2) readily adds [H(2)NMe(2)](+), HCl and F(3)CCOOH across its partial B=N double bond(s), thereby forming mono- or diadducts; treatment with 1-iso-propyl-2-mercaptoimidazole leads to a triply B-B-bridged propellane-like structure.

Constitutional Isomers of Alkanes
The linear isomer of an alkane is prefixed by the term “n”; hence a linear isomer of pentane is known as n-pentane. Based on the type of branching, some of the branched isomers are given...
