Phenyl trimethylstannyl

Trimethylstannyl chloride reacted smoothly with methyl and phenyl trimethylsilyl tellurium at 25°. Methyl trimethylstannyl tellurium (94% yield) and phenyl trimethylstannyl tellurium (89% yield) were isolated as involatile, yellow oils possessing foul, persistent odors1. 

Phenylarsine has been obtained from reaction of phenyl(trimethylstannyl)arsine and hydrogen bromide (equation 120) .

From Metallated Phosphines.— The polymeric ligand (4) has been formed from chloromethylated styrene-divinylbenzene copolymer and lithium diphenylphosphide. Trimethylsilylation of potassium phenyl-phosphide gave the phosphine (5), which on treatment with bromine gave phenylphosphorus. (Trimethylstannyl)phosphine (6) has been prepared in high yield from trimethyltin chloride and lithium tetraphosphinoaluminate. ...

The Pd°-catalyzed coupling reaction of j5-5-iodo-2 -deoxy-3, 5 -di-0-acetyluridine with 2-trimethylstannylthiophene and 2-phenyl-5-trimethylstannylthiophene has given the corresponding thiophene substituted nucleosides <91JHC529>. The unprotected 5-iodo-2 -deoxyuridine has also been coupled with 2-(trimethylstannyl)- or 2-(tributylstannyl)thiophene <91JMC2383> a Pd catalyst was used in a coordinating solvent (THE or dioxane), whereas in a noncoordinating solvent (toluene), a Pd° catalyst was found to be essential. 

The coupling partner, 2-phenyl-4-(trimethylstannyl)oxazole 1411 was readily prepared, in two steps, from 2-phenyl-4(5 /)-oxazolone. StiUe coupling of 1410 with 1411 using tetrakis-(triphenylphosphine)-paUadium[0] then afforded the model 2,4 -bis-oxazole 1412 in good yield. Similarly, 1410 was coupled with phenyltrimethyltin to generate 1413. 

Treatment of -caprolactone with 7V,7V-bis(trimethylsilyl)lithium amide and then with A-phenyl triflimide affords 2-triflyloxy-2-hexenolide (22). The latter is obtained in 89% yield <89CL1313> and can be regarded as a key intermediate in the syntheses of diverse 2-substituted 4,5,6,7-tetra-hydrooxepines. For instance, reactions of (22) with lithium dialkyl- or diphenylcuprates result in 2-butyl-substituted derivatives (23 R = Aik, Ph) <89CL1313>, while analogous interaction with hexa-methyldistannane gives 2-trimethylstannyl-4,5,6,7-tetrahydrooxepin (23 R = SnMcj) <91SL197>. 

Preparative Methods by lithiation of phenyl vinyl sulfide with lithium diisopropylamide, followed by silylation, or the base-induced elimination of 2-chloro-l-trimethylsilyl-l-phenylthioethane, or the lithiation of ethyl phenyl sulfoxide with LDA followed by silylation, or the Pd-catalyzed coupling reactions of trimethylstannyl phenyl sulfide with 1-bromo-1-trimethylsily lethylene. ...
