“…[28][29][30] Furthermore, in most cases, it is hard to remove the solvents due to the strong coordination between the solvents and the Na + ions. [9,28,[30][31][32][33][34][35] In this paper, we report an improved synthesis method for unsolvated NaB 3 H 8 , which involves an improved method to disperse Na and a refined procedure to produce fresh THF·BH 3 . The procedure avoids toxic reagents such as Hg and B 2 H 6 , employs simple setup, and thus facilitates large-scale production of NaB 3 H 8 .…”

“…We envisioned that the same procedure could also be used for reaction with the above described alkynyldeoxyribosides. In general, refluxing 6,9-(Me 2 S) 2 -arachno-B 10 H 12 [16] with anomeric mixtures of the alkynyldeoxyribosides 1a and 1b in toluene for 16 h gave the corresponding anomeric mixtures of carboranyl-C-deoxyribosides 2a and 2b (Scheme 2). However, it should be emphasized that despite the use of anomeric mixtures of alkynyldeoxyribosides, the corresponding mixture of products of carboranyl-C-deoxyribosides could be readily separated into the stereochemically pure substances by chromatography using silica gel columns.…”

“…Dimethyl sulfidearachno-nonaborane {(Me 2 S)B 9 H 13 } and (aminoalkylamine)-N-(aminoalkyl)azanonaborane(11) {H 2 N(CH 2 ) m H 2 NB 8 H 11 NH (CH 2 ) m NH 2 , where m = 4-6} were prepared as described in the literature. 14,18 The measurements for NMR ( 11 B, 1 H and 13 C) were carried out on a Bruker DPX 200 spectrometer. The chemical shifts δ are given in ppm relative to = 100 MHz for δ( 1 H) (nominally SiMe 4 ), and = 32.083 972 MHz for δ( 11 B) (nominally F 3 BOEt 2 ) in (THF-d 8 ).…”
