The most comprehensive one (so not "all" chemicals) that I've seen is the Aldrich website. By law they have to supply MSDS for everything they sell. However, they may ask for a lot number or the function may not work unless you're logged in as a customer.

This is straightforward. 4-Toluenesulfonyl Chloride is readily attacked by nucleophiles and allylamine is a good nucleophile. Dissolve 2.05 equivalents of allylamine (or 1.05 eq allylamine and 1 eq of an tertiary organic base such as triethylamine) in dichloromethane, cool in an ice/water bath (reaction is exothermic) then slowly add 1 eq of 4-...

What databases do you have access to? A Scifinder search would find literature references with no difficulty. A Google search finds this technical report which has the synthesis of tetraphenylporphyrin and the preparation of Fe(II) and Zn(II) complexes report here. The Cu(II) complex is prepared in this lab report here. The references in these reports should ...

Aminoxyl (trivial name: a nitroxyl radical or a nitroxide) denotes a radical functional group with general structure $\ce{R2N–O^•}$. It is well known that sterically unhindered aminoxyls baring $\alpha$‐hydrogens are unstable and undergo rapid disproportionation to nitrones and hydroxylamines (Ref.1: A new mechanism for the decomposition of $\alpha$‐hydrogen ...

The monoesters of succinic acid can be prepared using Steglich esterification method (Ref.1,2), which is specially suitable for alcohols with the $\ce{OH}$ functional group is in steric hindrance. In this method, dicyclohexylcarbodiimide (DCC) as the coupling reagent and 4-dimethylaminopyridine (DMAP) as a catalyst are used. The reference 1 gave a typical ...
