Abstract:
Reactions of LGeCl (L = CH[C(Me)N(Ar)](2); Ar = 2,6-iPr(2)C(6)H(3)) with KOtBu or LiR (R = 2-thienyl, N(H)Ar, PPh(2)) yielded the germanium(II) compounds LGeR [R = OtBu (1), 2-thienyl (2), N(H)Ar (3), PPh(2) (4)]. The reduction of (2-thienyl)(2)PCl with lithium afforded the diphosphane [(2-thienyl)(2)P](2) (5). The treatment of (2-thienyl)(2)PCl with LiAlH(4) or KHBtBu(3) led to the formation of (2-thienyl)(2)PH (6). The NHC-assisted reaction of LGeCl and 6 resulted in the isolation of LGeP(2-thienyl)(2) (7). This is the first example where NHC is used for eliminating HCl from compounds with P-H and Ge-Cl bonds. All solid products were characterized by elemental analysis, NMR and IR spectroscopy, and single-crystal X-ray structure determination.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
