This video about preparation diborane from sodium borohydride and Tin (II) chloride. When heated with no solvent, SnCl2 (anhydrous) and NaBH4 produce B2H6 with high yield (up to 94%).
==========
Reaction timing:
0:33 NaBH4 + O2
1:05 KBH4 + O2
1:33 NaBH4 + H2SO4
2:08 KBH4 + H2SO4
2:32 NaBH4 + SnCl2(anhydrous)
4:30 B2H6 + O2
5:01 NaBH4 + SnCl4(anhydrous)
