摘要：FIELD: chemistry. ^ SUBSTANCE: described is a compound of formula (I): , in which R1a and R1b independently denote a hydrogen atom; a primary or secondary alkyl group containing 1-8 carbon atoms; or a primary, secondary or tertiary alkyl group containing 2-8 carbon atoms and at least one ether bond; and R2a, R2b independently denote a hydrogen atom; a halogen atom; a primary, secondary or tertiary alkyl group containing 1-8 carbon atoms; or a primary, secondary or tertiary alkyl group containing 2-8 carbon atoms and at least one ether bond; and R3 denotes a hydrogen atom; a primary, secondary or tertiary alkyl group containing 1-8 carbon atoms; or a primary, secondary or tertiary alkyl group containing 2-8 carbon atoms and at least one ether bond; where, if R3 denotes a hydrogen atom, then at least two of R1a, R1b, R2a and R2b each independently denotes a primary, secondary or tertiary alkyl group containing 1-8 carbon atoms, where R1a and R1b do not denote a tertiary alkyl group; or a primary, secondary or tertiary alkyl group containing 2-8 carbon atoms and at least one ether bond; or at least one of R1a, R1b, R2a and R2b denotes a primary, secondary or tertiary alkyl group containing 2-8 carbon atoms and at least one ether bond; and where, if R3 denotes a primary alkyl group containing 1-8 carbon atoms, then at least one of R1a, R1a, R2a and R2b denotes a primary, secondary or tertiary alkyl group containing 1-8 carbon atoms, where R1a and R1b does not denote a tertiary alkyl group; or a primary, secondary or tertiary alkyl group containing 2-8 carbon atoms and at least one ether bond; and where, if at least two of R2a, R2b and R3 denote tertiary alkyl groups, then the tertiary alkyl groups are adjacent. Described also is a method of introducing one or more fluorine atoms into a desired compound, which involves bringing the fluorinating agent of formula (I) into contact with the desired compound under conditions which enable introduction of one or more fluorine atoms into the desired compound. ^ EFFECT: fluorinating agents having high thermal stability and reactivity with desired compounds. ^ 15 cl, 6 tbl, 64 ex
