The reduction of aldehydes to alcohols using lithium aluminium hydride (LiAlH4) is a fundamental, textbook organic chemistry reaction, making it common knowledge that requires no citation.
The claim states a well-established textbook reaction in organic chemistry (the reduction of aldehydes to primary alcohols by LiAlH4). None of the retrieved papers specifically target or test this exact standard textbook transformation, as they focus on unrelated advanced topics like natural product total synthesis, catalysis, and specific derivatives. Therefore, the claim is evaluated as common knowledge by definition and everyday observation in the field, with no specific citation needed from the provided set.
