Doubly Bonded Derivatives of Germanium

Structure and Reactions of an Isolable Ge=Si Doubly Bonded Compound, Tetra(t-butyldimethylsilyl)germasilene

“…Synthesis and structure of stable unsaturated compounds of heavy group-14 elements is one of the primary subjects of both experimental and theoretical main-group element chemistry; see reviews of experimental [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and theoretical aspects [20][21][22][23][24]. Since the first synthesis of stable digermenes and distannenes by Lappert et al [25][26][27] and a stable disilene by West et al [28], a number of heavy alkenes (R 2 E=ER 2 , E, E' = Si, Ge, Sn, and Pb) have been synthesized and their unusual structures and properties have been revealed.…”

Pyridine derived N-heterocyclic germylenes: A density functional perspective

“…In 1960s, organometallic chemistry encountered the start point of a series of revolutionary studies when the old idea of the unstable double bonds between heavier main group elements was broken down [1][2][3][4]. In this way, the valuable studies directed by Satgé introduced first transient intermediates having germanium doubly bonded to nitrogen (germanimines) in 1978 [5,6].…”

The reactions of germenes generated thermally from pivaloyl- and adamantoyltris(trimethylsilyl)germane with 1,3-butadienes

“…Many papers dealing with the synthesis of both transient and stable germenes have been published to date [1][2][3][4][5][6][7]. The methods reported for the synthesis of the germenes mainly involve the following routes: (1) reaction of germylenes with carbenes [8], (2) Peterson-type reactions [9], (3) [2+2] cycloreversion of four-membered rings [10,11], and (4) defluorosilylation [12] or defluorolithiation [13][14][15][16][17].…”
