The BCN-heterocyclic B−N chain compounds, the sodium and potassium salts of 3 and 4 anions (Na3, Na4, and K4), were synthesized by reactions of ethane 1,2-diamineborane (BH 3 NH 2 CH 2 CH 2 NH 2 BH 3 , 1) and propane 1,2-diamineborane (BH 3 NH 2 CH 2 CH 2 CH 2 NH 2 BH 3 , 2) with MH (M = Na and K). Then, the neutral B−N chain compounds 5 and 6 were prepared with dehydrogenation of [NH 4 ]3 and [NH 4 ]4, formed by metathesis reactions of Na3 and Na4 with NH 4 Cl or NH 4 SCN, respectively. Compounds 7 and 8, analog 5, were also prepared using pyridine and 4-methoxypyridine instead of NH 3 in 5. These synthesized compounds were characterized spectroscopically, and the singe-crystal structures of the Na3•18-crown-6 and K4•18-crown-6 adducts were determined. Furthermore, the reactions of Na3 and Na4 with cationic B−N chain compounds, [NH 3 BH 2 NH 3 ]Cl and [NH 3 BH 2 NH 2 BH 2 NH 3 ]Cl, could not form longer BCNheterocyclic B−N chain. The solubility of metal hydrides, the ability for proton abstracting, the basicity of Lewis bases, and the chelate effect may influence these reactions even though the reaction mechanism is not fully understood.

The design, synthesis, and applications of new boranes are eternal topics in boron chemistry. A new bis(borane)alkanethiolate salt, K[BH3S(CH3)BH3], was synthesized in high yield by the reaction of K with (CH3)2S·BH3 at room temperature. The formation mechanism was elucidated based on experimental and theoretical studies. The single-crystal structure of the K[BH3S(CH3)BH3]·18-crown-6 adduct was determined in which the B–S–B bonding information of K[BH3S(CH3)BH3] was illustrated for the first time. Using K[BH3S(CH3)BH3] as a starting material, KB3H8 was successfully synthesized.
