2,4,6‐Tri‐tert.butylphenyllithium reagiert mit Trimethoxy‐, Triethoxy und Triphenoxysilan zu den Dialkoxy‐ bzw. Diphenoxy‐(2,4,6‐tri‐tert.butylphenyl)‐silanen ArSiH(OR1)2 3–5 (Ar = 2,4,6‐Tri‐tert.butylphenyl, R1 = Me, Et, Ph). Die Einwirkung von Methyl‐oder n‐Butyllithium auf 3–5 liefert unter partieller oder vollständiger Substitution der OR1‐ Funktionen die Silane ArSiH(OR1)R2 7–11 und ArSiHR 22 12 und 13 (R2 = Me, Bu). Mit Lithium‐tert.butylamid reagiert 3 zu tert.Butylamino‐methoxy‐(2,4,6‐tri.butylphenyl)‐silan 14. Durch LiAlH4 wird 5 zu 2,4,6‐Tri‐tert.butylphenylsilan 6 reduziert. Die Umsetzung von 3 mit Antimontrifluorid führt zu 2,4,6‐Tri‐tert.butylphenyl‐trifluorisilan 2. Versuche, die Alkoxy‐ bzw. Phenoxygruppierungen in 3–5 durch Chlor auszutauschen, führten zur Spaltung der Silicium‐Kohlenstoff‐Bindung und Bildung von 1,3,5‐Tri‐tert.butylbenzen.

“…The possible existence of the monomeric form of LR 1 in solution led us to start investigating the potential of LR as a dienenophile for [2 ‫ם‬ 4] cycloaddition reactions (Scheme 1) [1,10]. It has been reported that the stable monomeric dithioxo(tri-tertbutylphenyl)phosphorane reacts with 2,3-dimethyl-1,3-butadiene in a [4 ‫ם‬ 2] cycloaddition process [11][12][13], and LR, as a dipolarophile, undergoes [2 ‫ם‬ 3] cycloaddition reactions with stable 1,3-dipolar compounds [10]. However, to our knowledge, there have been no attempts to utilize LR as a dienenophile or as an electrophile in syntheses of biologically active phosphorus heterocycles with P-S bond incorporation, and no report on biological activity of phosphorus-containing heterocycles obtained by employing Lawesson's reagent.…”
