  Conversion of the carbonyl group to CF2 using iodine monofluoride (IF)

  摘要：

  A novel method for the transformation of CO --> CF2 is described. The easily made hydrazone derivatives of the carbonyl moiety are reacted under mild conditions with IF prepared directly from the corresponding elements. Various hydrazones have been examined and compared with each other. Unsubstituted ones are usually the most suitable although they are not always easy to purify and store. N-Methyl- and N,N-dimethylhydrazones also give quite satisfactory results. The more easily made dinitrophenyl hydrazones (DNPs), semicarbazones, and tosylhydrazones also react, but the yields of the desired CF2 compounds are usually lower. Oximes could also be successfully reacted. The two main byproducts of the reaction are the parent carbonyl compounds, which can be recycled, and the alpha-iododifluoro derivatives. The latter upon treatment with LiAlH4 or Bu3SnH were reduced to the desired product, thus increasing the overall yields.

  通过α-甲硅烷基硫化物合成酮

  摘要：

  α-苯硫基硅烷（2）已经通过衍生自1-苯硫基-1-三甲基甲硅烷基烷（1）的阴离子（4）的烷基化而制备。这些阴离子（4）已经通过多种方法制备，包括：（1）的直接去质子化，萘锂置换苯硫基，在1-苯基硫-1-三甲基甲硅烷基乙烯中添加烷基锂（7），以及三丁基锡烷基部分的金属转移。通过萘二甲酸锂与苯硫醚的反应形成烷基锂，提供了从双（苯硫基）缩醛（8）到（2）的另一条路线。α-苯基硫代硅烷的替代途径（2）是还原相应的α-苯基磺酰基硅烷（15）; 这些反过来很容易从α-磺酰基阴离子的烷基化或甲硅烷基化获得。通过sila-Pummerer重排将α-苯基硫代硅烷（2）转化为O-三甲基甲硅烷基苯基硫代缩醛（18），尽管在某些情况下这会因硫化乙烯基（20）的形成而变得复杂。随后将（18）和（20）水解，得到酮（3）。

The formation of an alkyl-lithium by reaction of lithium naphthalenide with a phenyl sulphide provided an additional route to (2) from bis(phenylthio)acetals (8).
