✦ Synopsis

N-sulfinylacylamides R-C(ϭO)-NϭSϭO react with (CF 3 ) 2 BNMe 2 (1) to form, by [2ϩ4] cycloaddition, six-membered rings cyclo-(CF 3 ) 2 B-NMe 2 -S(ϭO)-NϭC(R)-O for R ϭ Me (2), t-Bu (3), C 6 H 5 (4), and p-CH 3 C 6 H 4 (5) while N-sulfinylcarbamic acid esters R-O-C(ϭO)-NϭSϭO react with 1 to yield mixtures of six-membered (cyclo-(CF 3 ) 2 B-NMe 2 -S(ϭO)-NϭC(OR)-O) and [2؉4] und [2؉2] Cycloadditionsreaktionen von N-Sulfinylcarbonsäureamiden mit (CF 3 ) 2 BNMe 2 .
