In the field of medicinal chemistry, the precise installation of a trideuteromethyl group is
gaining ever‐increasing attention. Site‐selective incorporation of the deuterated “magic …

An ion-neutral complex (INC) consists of an incipient ion coordinated to a putative neutral.
The two com-ponents of the INC are not connected by a normal co-valent bond, but …

When a molecule dissociates, three types of transport phenomena compete with
recombination of the fragments. Translational diffusion carries the cleavage products into the …

This is the first ab initio study of the energetics of the fragmentation mechanisms of
phthalate, by mass spectrometry, leading to protonated phthalic anhydride (m/z 149) …

Abstract Methoxy poly (ethylene glycol) 2000 (mPEG 2000) samples were substituted via
esterification reactions to convert the hydroxyl end group of the mPEG into potential initiators …

Collisional activation decomposition (CAD) spectra are interpreted as indicating that
formation of˙ CH2CH2CO+ (1) from ionized cyclopentanone, succinic anhydride arid …

The direct interaction of MoCl5 with a series of carboxylic acids has been elucidated for the
first time. The reactions proceed with release of hydrogen chloride and Cl/O interchange …

The reactions of the ion—neutral complex [CH3OH CH2 CH+ 2] have been examined by
unimolecular and bimolecular approaches. We conclude that the distonic ion CH3OH+ …

Electron impact ionization mass spectra of numerous alkenyl methyl ethers CnH2n‐1OCH3
(n= 3–6) recorded under normal (4 kV, 70 eV, 175° C) and low‐energy, low‐temperature (8 …

The reactions of ten metastable immonium ions of general structure R1R2C NH+ C4H9
(R1= H, R2= CH3, C2H5; R1= R2= CH3) are reported and discussed. Elimination of C4H8 is …
