An unexpected elimination of cyclopentadienide anion in the reaction of silacyclohexadienes with a bulky aryllithium

The reaction of silacyclohexadienes with an extremely hindered aryllithium, TbtLi (Tbt = 2,4,6-tris[bis(trimethylsilyl)-methyl]phenyl), gave no expected Tbt-substituted silacyclohexadienes but trihydrosilane, TbtSiH3, via the elimination of cyc

Generation and reactions of overcrowded diaryldilithiostannane and diaryldipotassiostannane

Exhaustive reduction of an overcrowded dibromostannane bearing two bulky aromatic substituents, Tbt(Dip)SnBr2 {Tbt = 2,4,6- tris[bis(trimethylsilyl)methyl]phenyl; Dip = 2,6-diisopropylphenyl}, with an excess amount of lithium naphthalenide in THF at -78°C gave the corresponding dilithiostannane, Tbt(Dip)SnLi2, the generation of which was confirmed by trapping experiments with some electrophiles together with 119Sn and 7Li NMR spectroscopy. The diaryldilithiostannane was found to be stable in solution under an inert gas below -25°C. The potassium analogue, Tbt(Dip)-SnK2, was also generated by the reduction of the dibromostannane in THF at -78°C by the use of KC8 as a reductant. The reactions of dilithiostannane and dipotassiostannane obtained with o-dibromobenzene did not give a stannacyclopropabenzene derivative but an unexpected cyclization product, a stannacyclobutabenzene derivative, in contrast to the reactions of the corresponding dilithiosilane and dilithiogermane, Tbt(Dip)ELi2 (E = Si, Ge), with o-dibromobenzene leading to the formation of the corresponding metallacyclopropabenzenes as stable crystalline compounds. A preliminary result of the synthesis of a tin-tellurium double-bond compound from the dilithiostannane is also presented. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.

Syntheses, structures and properties of kinetically stabilized distibenes and dibismuthenes, novel doubly bonded systems between heavier group 15 elements

The first stable distibene (RSb=SbR) and dibismuthene (RBi=BiR) were successfully synthesized by taking advantage of steric protection using an efficient steric protection group, 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (Tbt). Since it is quite difficult to investigate the reactivities of the distibene (TbtSb=SbTbt) and dibismuthene (TbtBi= BiTbt) in solution due to their extremely low solubility values, similarly overcrowded distibene and dibismuthene, BbtE=EBbt (E = Sb, Bi), with sufficiently high solubility were also synthesized using another bulky substituent, 2,6-bis[bis(trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]phenyl group (Bbt). The crystallographic analysis and spectroscopic studies of these stable dipnictenes led to the systematic comparison of structural parameters and physical properties for all homonuclear doubly bonded systems between heavier group 15 elements. In addition to these experimentally obtained results, theoretical calculations for these doubly bonded systems also revealed the intrinsic character of dipnictenes.

NEW ASPECTS OF ORGANOSELENIUM COMPOUNDS CONTAINING GROUP 14 ELEMENTS

The synthesis and reactivities of double bond compounds between Group 14 and Group 16 elements have been reported.Specifically the chemistry of M=X type compounds (C=Se, Ge=S, Sn=S, Sn=Se) are described.

Unusual 1,3-Rearrangement of Trimethylsilyl Group in the Reaction of 2,4,6-Trisphenyllithium

2,4,6-Trisphenyllithium (TbLi) gave a novel 1,3-silicon rearrangement product above -30 deg C, while the treatment of TbLi with some electrophiles also afforded 1,3-silicon rearrangement products even at -78 deg C probably via single electron transfer mechanism.

2,4,6-Trisphenyl, a New Sterically Demanding Group for Kinetic Stabilization of Unstable Compounds

The titled group (Ar) has been found to be very efficient for kinetic stabilization of a highly reactive N-thiosulfinyl group.The synthesis and the thermal and photochemical behavior of Ar-N=S=s are described.
