Hi, there's a reaction of 1-pyrrolidinocyclohexene with Ethyl vinyl ketone. I've already found out that the reaction of 1-pyrrolidinocyclohexene with Ethyl vinyl ketone is a Michael Reaction. But I don't get on which C-Atom the ethyl vinyl keton is added!? I hope someone can help me.

Thanks, you`ve really helped me

Hi hypervalent_iodine, I`m a teacher but not for chemistry, but it`s my hobby. I`ve heard some of my colleagues talk about this compound, and I wanted to be able to talk with them about this, so I tried to manage it to get the right oxidation numbers. But it has been too long since I was at school by myself. So please help me

Hi, what are the oxidation numbers of NaNi(IO6)? Ni is supposed to get the oxidation number +IV I hope someone can help me.

Hi, In the context of the synthesis of a coordination compound were added 1 mmol of copper (I) bromide with 1 mmol of 2,5-dimethylpyrazine and were stirred in acetonitrile. Here, a solid precipitated from X, which was filtered off and dried. An elemental analysis gave the following values​​: C: 28.65%, N: 11.12%, H: 3.21%. The content of Copper and bromine additionally by atomic absorption spectroscopy (AAS) was determined: (Cu: 25.25%, Br: 31.75%). As ratio formula I've got CuBrC6H8N2. But what's the molecul formula??? Can somebody help me??
