Tellurium dioxide, trimethylchorosilane, acetyl chloride, or acetyl bromide in glacial acetic acid generated a homogeneous solution. Addition of cyclohexene produced trans-2-halocyclohexyl tellurium trihalides of excellent purity in 70% yield. With dichloromethane or ethanol-free chloroform the same
A method is described for determining the composition of the carbon t&ra&loride/ acetic acid azeotroFe at pressures within the range lo-1,0C10 mm Hg absolute. Reduction in pressure descreases the percentage of acetic acid in the azeotrope. The cornpoSition at 760 mm absolute is found to be 164% acet
## Abstract Efficient and mild aldol additions of Ξ²βketo esters and malonates to aldehydes are described using two novel protocols in the presence of silicon tetrachloride and trimethylchlorosilane, respectively. Scope and limitations of the methods have been discussed. Moreover the stability of th
