Samples for PHIP−SAH and −HOT: 10 μl of TVOA (synthesized according to a protocol described below) or vinyl acetate (CAS 108‐05‐4, Merck) was dissolved in 600 μL of acetone‐d6 or chloroform‐d (Deutero GmbH) yielding a 100 mmol/L concentration. For PHIP experiments the catalyst [1,4‐Bis(diphenylphosphino)butane(1,5‐cyclooctadiene)rhodium(I) tetrafluoroborate] [1] (CAS: 79255‐71‐3, Strem Chemicals) was added to reach a concentration of 5 mmol/L. chloroform‐d and acetone‐d6 were dried by pouring it through a 3 cm column (ID=5 mm) of basic aluminium oxide powder and magnesium sulfate respectively directly before preparation of the samples. Both powders were dried overnight at 120°. Note, that even after drying, the residual HDO concentration was determined to approx. 1 mM. These samples were flushed by pH2 to produce hyperpolarization in the following stage.
Samples for reference NMR spectra: NMR spectra of the following compounds dissolved in chloroform‐d or acetone‐d6 were measured at concentrations of 10–100 mM: vinyl acetate (CAS: 108‐05‐4), ethyl‐acetate (CAS: 141‐78‐6), triethyl orthoacetate (CAS: 78‐39‐7), acetaldehyde (CAS: 75‐07‐0), 2‐chloroethanol (CAS: 107‐07‐3), ethyl alcohol (CAS: 64‐17‐5). All compounds were purchased from Merck. These samples and the corresponding spectra were used to assign the products of the TVOA hydrogenation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
