Tolerant: Alkylmagnesium reagents can be synthesized from alkenes through a sequence of hydroboration and subsequent boron–magnesium exchange using a method that tolerates different functional groups (see scheme). The resulting alkylmagnesium reagents can be used in carbon–carbon bond forming reactions, such as alkylation reactions or transition‐metal‐catalyzed cross‐coupling reactions.
The present invention generally relates to methods of inhibiting ethylene responses in plants and plant materials, and particularly relates to methods of inhibiting various ethylene responses including plant maturation and degradation, by exposing plants to cyclopropene derivatives and compositions thereof wherein: 1) at least one substituent on the cyclopropene ring contains a carbocyclic or heterocyclic ring, or 2) . a substituent contains silicon, sulfur, phosphorous, or boron, or 3) least one substituent contains from one to four non-hydrogen atoms and at least one substituent contains more than four non-hydrogen atoms.
The present invention provides a compound of the following formula, salts, racemates, diastereomers, enantiomers, esters, carbamates, phosphates, sulfates, deuterated forms and prodrugs thereof.
Also provided is the use of these compounds as antibacterials, compositions comprising them and processes for their manufacture.
