  Hydrogen peroxide and persalt washing or disinfecting compositions perform comparatively ineffectively at ambient to low operating temperatures. More effective washing/disin- fection processes are obtained by employing according to the instant invention there with a peroxyacid generator selected from compounds having the general formula (I):- in which R, and R2 and R3 often are hydrogen, R6 is often hydrogen or methyl and R. and R5 are often methyl or phenyl. R3 or R5 can each also represent a difunctional groupterminat- ing at its other end in a second gem-diester group or in an enol ester group. Especially preferred peroxyacid generators include 1,1,5-triacetoxypent-4-ene, 1,1,5,5-tetraacetoxy pentane, the corresponding butene and butane compounds, ethylidene benzoate acetate and bis (ethylidene acetate) adipate.

• Synthesis and structure of highly polarised double-bond compounds derived from S-proline
  作者：R.Alan Aitken、Karamat Ali、Noemı́ de Elena、Philip Lightfoot

  DOI：10.1016/s0040-4039(00)01372-1

  日期：2000.10

  Reaction of the chiral iminium salt 3 with stabilised carbanions gives the compounds 4-9 containing a highly polarised double bond. The extent of this polarisation is determined by variable temperature H-1 NMR studies, comparison of C-13 NMR chemical shifts and an X-ray structure determination. (C) 2000 Elsevier Science Ltd.
