The rhenium(I) cyclovinyl ether complexes [(triphos)Re(CO)(2){C=CHCH2(CH2)(n) O}]BF4 [triphos = MeC(CH2PPh2)(3); n = 1, 2] have been synthesized through the reversible and regioselective deprotonation of the corresponding 2-oxacyclocarbene complexes [(triphos)Re(CO)(2){=CCH2CH2(CH2)(n)CH2O}]BF4 (n=1, 2). The structure of the octahedral 2-oxacyclohexylidene complex [(triphos)Re(CO)(2)(=CCH2CH2CH2CH2O)]BF4 has been determined by a single-crystal X-ray diffraction analysis.

Abstract
The rhenium(I) cyclovinyl ether complexes [(triphos)Re(CO)(2){C=CHCH2(CH2)(n) O}]BF4 [triphos = MeC(CH2PPh2)(3); n = 1, 2] have been synthesized through the reversible and regioselective deprotonation of the corresponding 2-oxacyclocarbene complexes [(triphos)Re(CO)(2){=CCH2CH2(CH2)(n)CH2O}]BF4 (n=1, 2). The structure of the octahedral 2-oxacyclohexylidene complex [(triphos)Re(CO)(2)(=CCH2CH2CH2CH2O)]BF4 has been determined by a single-crystal X-ray diffraction analysis.File in questo prodotto:
