"Educational review articles": How find these
I've seen them called 'tutorial reviews'. Since you say you're in chemistry, see for example Chem Soc Rev's tutorial reviews, as they call them here:

Here's an extract from how they define 'tutorial review':

Tutorial reviews are concise, authoritative overviews of important contemporary topics in the chemical sciences. They should appeal to advanced undergraduates, the general research chemist who is new to the field, as well as the expert. They provide a solid introduction to the development of a subject, the latest breakthrough results and their implications for the wider scientific community.
Accessible: To advanced undergraduate students and beyond. Tutorial reviews are often used in advanced undergraduate and Master’s studies.
Authoritative: An essential introduction to the field will lay the foundation of knowledge in the area with approximately 25 seminal citations, serving as a springboard to further reading, followed by the most important recent advances.
Jargon free: Specialist terms and symbols should be defined and fundamental ideas simply explained.

I guess that's what you're thinking of?
