Syntheses of the dimers of axial 5‐methyl‐2‐dithiazinyllithium ( 4 ) and equatorial 5‐methyl‐2‐diethiazinyllithium‐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 1 H‐, 13 H‐, 13 C‐, 11 B‐, and 7 Li‐NMR study of th reactions of 4 and 5 with BH 3 S(CH 3 ) 2 , BH 3 —THF, and CH 3 I is presented.
