## Abstract The potassium salt K(C~5~H~5~BMe) (8) can be obtained from 2‐(Me~3~Sn)C~5~H~5~BMe (7)/KO__t__Bu in toluene in essentially quantitative yield. Metalation of 1‐(dimethylamino)‐3‐methylene‐1,2,3,6‐tetrahydroborinine (9) with MN(SiMe~3~)~2~ (M = Na, K) in toluene afforded the unsolvated sal
