The rhenium(I) cyclovinyl ether complexes [(triphos)Re(CO)2{C /CHCH2(CH2)nO}]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)nCH2O}]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)nO}]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)nCH2O}]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:
