There is much more solvent attack than was claimed for I bromo-1-methyl-2.2-diphcnylcyclo-propane 20. Instead, the extent of s agrees with that for eyelopropyl bromide itself 52.98. Together with the linding that there is less than 0.52 s in a reaction ol n-hexyl bromide in Did 52. these linding disprove a set of hypotheses suggested by Walborsky I09 (a) the only radicals that attack the solvent are those that desorb (b) their inevitable fate is solvent attack and (c) fewer eyelopropyl radicals than typical alkyl radicals desorb. These hypotheses predict more solvent attack in reactions of typical alkyl than eyelopropyl halides, opposite from observations 52. ...

Predict the product of the reaction if CH3-S-CH2CH2CH2CH2-Br is heated in a polar organic solvent, such as methanol. Similarly, what would be the product for hexyl bromide in methanol (In hexyl bromide, note that the S has been replaced by a CH2 group.)

For benzylation, the greatest preference for reaction next to the axial substituent (about 9 1) has been obtained by reaction in benzyl bromide as solvent for both tributylstannyl ethers109 and for dibutylstannylene acetals,110 with still greater preferences using larger alkyl groups in the dialkyl-stannylene acetals, such as hexyl or neopentyl groups.110 Methylation reac-... 

The a proton of a substituted cyclopropane is also rendered acidic if the substituent is attached to the ring by C-P bonds. A few reports have appeared on a-substitution in such compounds.(Cyclopropyl)triphenylphosphonium bromide was converted to a (1-ethoxy-carbonylcyclopropyl)triphenylphosphonium salt 18 in 80% yield by sequential treatment with lithium diisopropylamide and ethyl chloroformate. Furthermore, some diethyl cyclopropyl-phosphonates were converted, in some cases in excellent yield, to diethyl (1-hydroxymethyl-cyclopropyl)phosphonates by treatment with lithium diisopropylamide followed by addition of an aldehyde." Thus, typically, diethyl 2-hexylcyclopropylphosphonate gave diethyl 2-hexyl-l-[hydroxy(phenyl)methyl] cyclopropylphosphonate (19b) in 90% yield on reaction with benzaldehyde. ° Other electrophiles such as acetone, acetyl chloride, acetic anhydride, and ethyl acetate, were not sufficiently reactive to undergo addition to the anion.
