Syntheses, Structures and Properties of Kinetically Stabilized Distibenes and Dibismuthenes, Novel Doubly Bonded Systems between Heavier Group 15 Elements.
dibismuthene, BbtE=EBbt (E = Sb, Bi), with sufficiently high solubility were also synthesized using another bulky substituent, 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl group (Bbt). The crystallographic analysis and spectroscopic studies of these stable dipnictenes led to the systematic comparison of structural parameters and physical properties for all homonuclear doubly bonded

also succeeded in the synthesis of the firststable distibene (RSb[double bond, length as m-dash]SbR) and dibismuthene (RBi[double bond, length as m-dash]BiR) by taking advantage of efficient steric protection groups, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt) and 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl (Bbt), and revealed their structures and properties systematically

Deselenation of an overcrowded triselenatribismane, 2,4,6-2,4,6-tris[bis(trimethylsilyl)methyl]phenyl}-l,3,5-triselenatribismane, with hexamethylphosphorous triamide resulted in the formation of the first stable dibismuthene TbtBi=BiTbt; Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl}, i. e. the doubly bonded compound consisting of the heaviest stable element in the periodic table, as deep purple
