Carbene-insertion noble gas compounds: FKrCF and FXeCF

Existence of noble gas-inserted phosphorus fluorides: FNgPF2and FNgPF4with Ng–P covalent bond (Ng = Ar, Kr, Xe and Rn)

“…[71][72][73][74][75][76][77] Khriachtchev et al fruitfully synthesized and categorized the noble-gas inserted molecule, HXeOBr, 42 through the IR spectroscopic technique, which was theoretically predicted by our group earlier. 31 Recently, FKrCF and FXeCF were synthesized in solid krypton and xenon matrices, 9 respectively, at cryogenic temperatures by Feldman and co-workers, which were also theoretically predicted by our group earlier. 78 It is worth mentioning that Ng interacts with the P atom in various ways under different chemical environments, e.g., van der Waals interactions exist between Ng and P atoms in the Ne-PF 3 , 79 Ar-PF 3 , 80,81 and Kr-PF 3 81,82 complexes, while conventional Ng-P chemical bonding persists in FNgY (Ng = Kr, Xe; Y = N, P) 58 molecules, which has been reported by us recently.…”

“…However, in the ground-breaking paper by Bartlett, the formation of [Xe + PtF 6 − ], 1,4 and subsequently the fluorination of xenon 5,6 was successfully accomplished. This discovery introduced the exciting world of noble gas chemistry, 7–15 which has been revisited several times in the past decades, resulting in the observation of numerous molecules containing chemically bonded noble gas atoms. 16–51…”

Long‐bonding and effects of carbon hybridization on the bonding of MNgC compounds (M = Cu, Ag, Au)

“…It has been found that the stability and reactivity of oxonium salt [RXe] + Y À depend on the properties of organic group R and anion Y À . Many Xe C compounds have been theoretically predicted and experimentally prepared, such as C 6 F 5 XeZ(Z = F, Cl, CN) [20], C 2 H 3 COONgH(Ng = Ar, Kr, and Xe) [21], HNgC n N [22,23], XRgCO + (X = F, Cl, Rg = Ar, Kr, Xe) [24], NgMCp + (Ng = He Rn, M = Be Ba, and Cp = η 5 C 5 H 5 ) [25], HXeCCXeHÁ Á ÁHCCH [26], OBNgCN (Ng = Kr, Xe, Rn) [27], Ng 2 @C 60 (Ng = He Xe) [28], FNgCF(Ng = Kr, Xe) [29], RXeXeR(R = CN, NC, CCH, BS) [30], and (Ng) n NC + [31] and so on.…”

“…During this time, several key works contributed to the development of noble gas chemistry, including Pauling's theoretical prediction of the existence of the noble gas fluorides in 1933 [1], Neil Bartlett's successful synthesis of Xe + [PtF 6 ] − in 1962 [2], and Räsänen's synthesis of HArF using HF photocatalysis in Ng matrix in 2001 [3]. In recent years, many compounds formed by noble gases and various chemical elements have been synthesized experimentally and/or predicted theoretically [3–37]. It seems that noble gases can bond with every element in the periodic table and plug into any bond to form insertion compounds.…”
