(Dimesitylphosphino)ferrocene (FcPMes2) (1) reacted with HB(C6F5)2 (2 equiv) by disproportionation to give adduct FcPMes2·H2B(C6F5) (4) plus B(C6F5)3, whereas 1-(dimesitylphosphino)-1′-vinylferrocene (2) was cleanly hydroborated with HB(C6F5)2 to

The HOMO–LUMO energy gap of germylenes bearing CNHC∧Namido chelate ligands has been calculated in order to find suitable candidates for the activation of small molecules. Identified as promising structures, intramolecularly NHC-stabilized three-c

Dimesitylphosphinoisoprene 9a reacts with a series of R-B(C6F5)2 boron Lewis acids by isomerization and subsequent 1,4-P/B addition to give the heterocyclic phosphonium/borate zwitterionic products 13. Subsequent hydride abstraction from the isopreny

The monoalkylated or monoarylated o-phenylenediamines 1a–d (1a, R = t-Bu; 1b, R = adamantyl; 1c, R = phenyl; 1d, R = mesityl) react via transamination with Ge[N(SiMe3)2]2 or Sn[N(SiMe3)2]2 to give the protic benzimidazolin-2-germylenes 2a–d or th

Reaction of the –CH2OSiMe3 substituted allyldimesitylphosphane 5 with HB(C6F5)2 resulted in a hydroboration/(C6F5)2BOSiMe3 elimination sequence to give the phosphinomethyl substituted cyclopropane derivative 9, probably via a phosphiranium type int

A rigid ditopic benzobisgermylene, 4a, was prepared by the reaction of the 1,2,4,5-tetra(alkylamine)benzene 3a and Ge[N(SiMe3)2]2. The analogous reaction of two 1,2,4,5-tetra(alkylamine)benzenes, 3b,c, with Sn[N(SiMe3)2]2 led to the oxidation of the

Four N,N′-disubstituted 1,2-diaminobenzes (1a: R = t-Bu, 1b: R = adamantyl, 1c: R = Ph, 1d: R = Dipp) have been prepared and reacted with E[N(SiMe3)2]2 (E = Ge, Sn) to give the benzannulated N-heterocyclic germylenes 2a–d and stannylenes 3a–d.
