Carbinols cyclopropylcarbinols

These electrophilic conjunctive reagents require donor reactants. The cyclopropyl-carbinols as precursors to cyclobutanones arise by simple addition of organometallics. For example, the cyclobutanone 47 derives by addition of vinyllithium to 44 followed by rearrangement with aqueous fluoroboric acid 92). In some cases, this route to cyclopropylcarbinols is preferred. Addition of 41 to aldehydes or ketones... 

Unsubstituted and substituted aryl- and heteroarylcyclopropyl (methyl-1,2,4-triazolyl)-carbinols have been prepared and used as fungicides and plant growth regulators. Thus the cyclopropylcarbinol 97 (R1 =p-ClC6H4> R2= SEt) inhibited the growth of rice, cotton and soybean, and protected apple against Ven-...
