In nature, boron is composed of a mixture of two stable isotopes, 10B (19.78%) and 11B (80.22%). The isotopical 10B-enriched compounds play important roles in many fields, such as the nuclear industry and cancer radiate treatment. Therefore, the syntheses of such kind of compounds is of important significance. These isotopical 10B-enriched compounds can be prepared from 10B-enriched boranes, however, the synthetic methods of such boranes are few. Herein, the synthetic methods of 10B-enriched Na10BH4, THF•10BH3, DMS•10BH3, DMA•10BH3, NH310BH3, Me3N•10BH3, Ph3P•10BH3, and IPr•10BH3 were developed. Firstly, Na10BH4 was synthesized with commercially available 10B(OH)3 as starting material based on the modified literature methods. Then the reaction of Na10BH4 and I2 provided 10B2H6, which could rapidly react with different Lewis bases to afford corresponding L•10BH3. Undoubtedly, these approaches provide convenient ways for the synthesis of 10B-enriched compounds.
