Waschbusch, Rachel published the artcileA new route to α-fluorovinylphosphonates utilizing Peterson olefination methodology, Formula: C5H10Cl3O3P, the publication is Tetrahedron (1996), 52(45), 14199-14216, database is CAplus.
Several α-fluorovinylphosphonates were synthesized from the Peterson olefination reaction applied to both aldehydes and ketones in conjunction with α-lithiated-α-fluoro-α-trimethylsilymethylphosphonate. The reaction with aldehydes gives mainly the E-isomer whereas reaction with ketones gives mainly the Z-isomer. The authors propose a closed transition state to explain the results.
Tetrahedron published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C15H18BF3O2, Formula: C5H10Cl3O3P.
