Allylation using allylstannanes and allylsilanes Flashcards
1
Q
What type of metals are Sn and Si?
A
Type II. Reaction proceeds through open TS.
2
Q
What is the favoured stereochemical outcome?
A
Syn stereoselective, irrespective of double bond geometry
3
Q
How does allylation proceed?
A
Through SE2’ mechanism. Alignment of C-Sn/Si with developing positive charge on B-carbon provides stabilising effect in T.S.
