Abstract: The invention relates to compounds represented by Formula (1): wherein Ra is alkyl or the like; Rb is fluorine or —CF3; A is 1,4-cyclohexylene, 1,4-phenylene or the like; Z is a single bond, alkylene or the like; Y is a single bond, alkylene or the like; and m and n are an integer of approximately 0 to approximately 5.
Abstract: A method of reacting a toluenesulfonyl-terminated polyoxyethylene compound having the formula CH3—C6H4—SO2—(O—CH2—CH2)n—O—R1 with an ammonium salt having the formula NR24X to form a compound having the formula X—CH2—CH2—(O—CH2—CH2)n-1—R3. The value n is a positive integer. X is a halogen, cyanide, cyanate, thiocyanate, or azide. R1 is a terminating group. Each R2 is hydrogen or an alkyl group. —R3 is —O—R1 or —X.
Abstract: (Per)haloethers having formula: X-(Rf)L-O—CF2CF2—O—CX1X2—CFX3X4 , ??(I) process for obtaining them and hypofluorites usable in the synthesis of said (per)haloethers.
Abstract: A process of making poly(glycidyl azide) and 3,6 -dioxadecyl thiocyanate using a phase transfer catalyst that permits the recovery and recycle of the phase transfer catalyst.
