    摘要: The invention relates to the use of substances for the production of anions suitable for charge transfer reactions in mass spectrometers, particularly for the fragmentation of multiply positively charged biopolymer ions by electron transfer or for charge reduction by proton transfer. Diketones, particularly α-diketones, are proposed as a newly found class of substances which can be used both for the production of radical anions for electron transfer dissociations (ETD) with a high yield of fragment ions and also for the production of non-radical anions for the charge reduction of multiply charged analyte ions by proton transfer reactions (PTR). These substances have favorable properties in terms of their handling and the associated analytical methods: they are largely nontoxic, cover a favorable range of molecular masses, and their volatility means that they can be stored in unheated containers outside of the vacuum system, which facilitates the refilling of the containers.

    摘要: The presently disclosed subject matter demonstrates that a spin state which has zero magnetic resonance signal, but an extremely long lifetime, can be used to store magnetization, which can then be recovered into an observable transition. Coupled with hyperpolarization techniques, this permits the preparation of a wide range of contrast agent molecules for use in magnetic resonance imaging (MRI) techniques that have long effective relaxation time.

    摘要: Disclosed is a process for preparing a β-diketone compound such as 2,6-dimethyl-3,5-heptanedione, which comprises reacting an ester compound such as an alkyl isobutyrate with a ketone compound such as 3-methylbutanone in the presence of an alkali metal alkoxide as a catalyst. The process comprises a step 1 in which an ester compound CR1R2R3COOQ is reacted with a ketone compound CR4R5R6COCH2R7 using an alkali metal alkoxide catalyst to give a β-diketone compound CR1R2R3COCHR4R5R6. (In the formulae, R7 is hydrogen or an alkyl group of 1 to 4 carbon atoms while others are each independently hydrogen or an alkyl group of 1 to 3 carbon atoms, and at least one of R1 to R6 is hydrogen.)
