A New Lithium 5-Methyl-1,3-dithia-5-azacyclohex-2-ylborate-5-Borane and Two Dimeric 5-Methyl-1,3-dithia-5-azacyclohex-2-yllithium Compounds - Stereochemistry and Reactivity

Article abstract of DOI:10.1002/cber.19971300622

Syntheses of the dimers of axial 5-methyl-2-dithiazinyllithium (4) and equatorial 5-methyl-2-dithiazinyllithium-5-borane (5), and lithium 5-methyl-2-dithiazinanylborate-5-borane (6) are reported. Compounds 4, 5, and 6 are configurationally and conformationally stable. The ¹H-, ¹³C-, ¹¹B-, and ⁷Li-NMR study of the reactions of 4 and 5 with BH₃-S(CH₃)₂, BH₃-THF, and CH₃I is presented.
