reported in ppm downfield of tetramethylsilane as internal
standard. 31P{1H} NMR chemical shifts are relative to an
external standard, 85% H3PO4 in D2O. Solid state 31P{1H}
NMR studies were performed on a Chemagnetics CMX400
spectrometer (operating at 161.03 MHz) using a cylindrical
rotor and spun at 3 kHz; chemical shifts are reported relative to
NH4H2PO4. Elemental analysis was performed with a Perkin-
Elmer 2400 Series II CHNS analyser. Gases were quantitatively
analysed by gas chromatography (Shimadzu GC-8A, GC-14B)
using the internal standard method.

[Ru(ꢁ2-C2H3OPh)(cod)(depe)] 2a. A typical example is given:
depe (0.125 cm3, 0.553 mmol) and phenyl vinyl ether (0.067
cm3, 0.55 mmol) was added to a solution of [Ru(cod)(cot)]
1 (171.2 mg, 0.5435 mmol) in 3 cm3 of toluene. The reaction
mixture was stirred at room temperature for 24 h. After volatile
materials were removed, the residual dark yellow oil was
crystallised from warm hexane to give white crystals which were
dried under vacuum to yield 2 (255.0 mg, 0.4779 mmol): yield
