Carbanions - BYJU'S
What is a Carbanion? A carbanion can be defined as a negatively charged ion in which a carbon atom exhibits trivalence (implying it forms a total of three bonds) and holds a formal negative charge whose magnitude is at least -1. byjus.com

Kornblum–DeLaMare rearrangement
Reaction mechanism In the reaction mechanism for this organic reaction the base abstracts the acidic α-proton of the peroxide 1 to form the carbanion 4 The reaction course in this rearrangement is different because ether cleavage with carbanion formation is unfavorable. wikipedia.org
