Conclusions

  1. 1.

    The comparative reactivity of mixed alkyl vinyl and alkyl acetylene compounds of aluminum of the type of R2AlCR'≡CHR" and R2AlC≡CR' was studied by the method of competitive reactions.

     
  2. 2.

    The vinyl and acetylene groups in these compounds are more reactive than alkyl groups in reactions with halogens, CO2, alcohols, and aldehydes.

     
  3. 3.

    The vinyl and acetylene groups in these compounds lower the reactivity of the alkyl groups at the same aluminum atom, in comparison with aluminum trialkyls.

     
  4. 4.

    The vinyl groups in compounds of the type of R2A1CR'≡CHR are more reactive than the alkyl groups in aluminum trialkyls AlR3.

     
  5. 5.

    The comparative reactivity of the acetylene groups in compounds of the type of R2AlC ≡CR′ and alkyl groups in aluminum trialkyls depends on the nature of the reagent: acetylene groups are more reactive with Br2 and i-C3H7OH, while alkyl groups are more reactive with I2 and CO2.

     
  6. 6.

    The vinyl groups in compounds of the type of R2AlCR′ =CHR″ are more reactive than the acetylene group in R2AlC≡CR'.
