摘要：

Addition of PhC=CH to hypho-type species [(R'H2N)B8H11NHR] proceeds readily with the displacement of R'NH2 to give corresponding N-bridged arachno ten-vertex species [6,9-mu-(NHR)-5-Ph-arachno-5,10-C2B8H10] (15 - 34%), for which DFT structural and GIAO B-11 nuclear shielding calculations suggest the syn configurations that have the R and Ph groupings on the same side of the molecule.
