A process for the preparation of 3-phenyl/heteroaryl-6-phenoxy-8-alkylamino-imidazo[1,2-b]pyridazine derivatives and intermediates of this process. A crystalline form of N-cyclopropyl-4-{6-(2,3-difluor-4-methoxyphenoxy)-8-[(3,3,3-trifluorpropyl)amino]imidazo[1,2-b]pyridazin-3-yl}-2-methylbenzamide. The compounds are inhibitors of the Mps-1 kinase (Monopolar Spindle 1 kinase; also known as Tyrosine Threonine Kinase, TTK).

A novel agent for introducing a protecting group for a hydroxy group and/or a mercapto group that can be introduced and removed under mild conditions is provided. The agent for introducing a protecting group for a hydroxy group and/or mercapto group of a substrate compound having the hydroxy group and/or mercapto group is represented by the following formula (I), wherein A represents a ring structure having 1 to 5 rings in which two carbon atoms of an adjacent benzene ring are included, the ring structure comprises a substituted or unsubstituted five-membered ring or six-membered ring and optionally include a heterocycle; each of R.sup.1, R.sup.2, R.sup.3, and R.sup.4 is independently a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms; and X is a halogen atom or OSO.sub.2R.sup.5 (R.sup.5=an aryl group or an alkyl group).

A method of depolymerising a lignin includes oxidising the lignin to provide an oxidised lignin wherein benzylic —OH of β-O-4 linkages have been converted to carbonyl. The oxidised lignin is depolymerised with a metal selected from the group consisting of zinc, magnesium, aluminium and titanium or mixtures thereof, in the presence of an ammonium salt or carbon dioxide. Also described are methods for manufacturing phenolic products from lignin and a method for the cleavage of a β-O-4 linkage in a substrate.

Disclosed herein is a method of reducing or disproportionating peroxide, comprising combining an organic chalcogenide, an iron salt, and the peroxide in the presence of an additional reductant, which can be the organic chalcogenide. The method can be used to, e.g., prepare alcohols from peroxides and to disproportionate hydrogen peroxide into water and oxygen.

There is disclosed an electrochemical deblocking solution for use on an electrode microarray. There is further disclosed a method for electrochemical synthesis on an electrode array using the electrochemical deblocking solution. The solution and method are for removing acid-labile protecting groups for synthesis of oligonucleotides, peptides, small molecules, or polymers on a microarray of electrodes while substantially improving isolation of deblocking to active electrodes. The method comprises applying a voltage or a current to at least one electrode of an array of electrodes. The array of electrodes is covered by the electrochemical deblocking solution.
