Ether complexes of tungsten with two different binding modes: An O-bound ether and an η2-(C=C) vinyl ether. Evidence for C-H?O hydrogen bonding of vinylic C-H groups

The reaction of PhCH(OCH3)2 with Cp(CO)3WH and HOTf gives [Cp(CO)3W(PhCH2OCH3)]+OTr - The structure of this benzyl methyl ether complex was determined by single crystal X-ray diffraction and was shown to have the ether bonded to tungsten through the oxygen. This compound was isolated as a kinetic product of the reaction; it decomposes in solution by releasing free PhCH2OCH3 and forming Cp(CO)3WOTf. An analog with the BAr′4- counterion [Ar′ = 3,5-bis(trifluoromethyl)phenyl] is more stable. The reaction of the vinyl acetal CH2=CHCH(OEt)2 with Cp(CO)3WH and HOTf produces [Cp(CO)3W(η2-EtOCH=CHCH3)] +OTf-, in which the ether is bonded to tungsten through the C=C bond of the vinyl ether. The crystal structure of this compound shows that the W-C(OEt) distance (2.69(3) A?) is significantly longer than the W-C(CH3) distance (2.37(3) A?). There are weak C-H?O hydrogen bonds between both vinyl CH's and oxygens of triflate counterions. Evidence is presented that some of these weak hydrogen bonds are maintained in CD2Cl2 solution but not in CD3CN.
