The oxidative cyclization of aromatic and heteroaromatic nitriles with alkynes in the presence of a catalytic amount of [{RuCl2(p-cymene)}2], Cu(OAc)2·H2O and KPF6 in acetic acid under air gave isoquinolones in good to excellent yields.

In the RuCl2(p-cymene)/PPh3 catalysed regioselective allylic alkylation of monosubstituted allyl acetates with malonate anion, the selective substitution at the position originally substituted with acetate was observed.

Mark: This is a prospective, observational study to determine if negative electrocardiography (ECG) performed while the patient is having chest pain can reliably rule out coronary disease. Eligible participants presented to the emergency department with chest pain and had normal initial ECG. Eligibility criteria also included age older than 25 years, two negative troponins over six hours, and a...

Thymbra spicata L. (zahter) bitkisi, başta Hatay oılmak üzere, Gaziantep, Kilis ve ülkemizin akdeniz iklim kuşağında doğal olarak yetişmekte genellikle baharat kullanılmaktadır. Bu çalışma, ilinden toplanan bitkilerinin uçucu yağ oran kompozisyonlarını belirlemek amacıyla yapılmıştır. Uçucu içeriklerini analiz etmek için GC-MS (Gaz Kromatografi Kütle Spektrometresi) kullanılmıştır. çalışmada ku...

The title compound, [RuCl2(C10H14)(C14H15OP)], is an Ru(II) complex in which an η(6)-p-cymene ligand, two chloride anions and the P atom of an ethoxydiphenylphosphane ligand form a piano-stool coordination environment about the central Ru(II) atom.
