The first examples o f 1,7,1,4,7,8-dialkyltriazaborabicyclo[3.3.0]octane.s 1-3 [R = isopropyl ( I ) , R = 1phenylbenzyl (Z), R = 1-methylbenzyl (3)] are reported. The bulky substituents prevent dimerization and make the syntheses feasible. The structures and confornations of the new compounds were s
The two C-P distances iirc 1.76 A and arc thus significantly shorter than those for C-P single bonds; the C-P-C angle is 105' (for comparison, (H3C),P: 1.87 and 100' [2], and (C6HS)3P: 1.83 A and 103" 131).
adducts 11 and 12 derived from compounds 1 and 2, respectively, and the dihydride-(2-guanidinobenzimidazole-N,NЈ)borate 13 and dihydride-(2-guanidino-1methyl-benzimidazole-N,NЈ)borate 14 were observed by 11 B NMR. The results show that 2-guanidinobenzimidazole gives stable borate heterocycles with a
