The First Kinetically Stabilized Stannaneselone and Diselenastannirane:  Synthesis by Deselenation of a Tetraselenastannolane and Structures

Heterocarbenoids of germanium and tin and their polyhedral oxidation products: The case for thermodynamic product control in Group 14 chalcogenides

“…If one were to find kinetically-stabilized terminal Group 14 chalcogenides, then it would certainly have to be among this class of compounds. We, therefore, scrutinized all available data on ''heavy ketones" for definitive evidence of kinetic stabilization [42][43][44][45][46][47][48][49][50][51][52][53], namely the conversion of monomeric to dimeric chalcogenides at elevated temperatures. But among the approximately one dozen of such terminal chalcogenides described in the literature we found circumstantial evidence of kinetic stabilization in only one case [53].…”

Synthesis of chelating diamido Sn(iv) compounds from oxidation of Sn(ii) and directly from Sn(iv) precursors

“…Crystals suitable for X-ray crystallographic analysis were grown from saturated n-hexane solution (3, 4, 5 monoclinic, [10][11][12][13]15), saturated toluene solution (1, 2, 5 triclinic, 14, 17-19) or saturated diethyl ether solution (16). The crystals were covered in an inert oil and then transferred to the cold stream of the diffractometer.…”

Heteroatom chemistry in Asia: Past, present, and future

“…Telluroketone 15, which is stable in solution, was also obtained by the same group [15]. For other heavy ketones, silanethione 16 [16], germanethione 17 [17], germaneselone 18 [18], germanetellone 19 [19], and even stannaneselone 20 [20] were synthesized by Tokitoh and Okazaki et al using combinations of Tbt and Tip groups or Tbt and Dipt groups or Bbt and Tipt as steric protecting groups. Recently, Tokitoh et al reported stannanetellone 21 [21] stabilized by Bbt and Tipt groups (Scheme 5).…”
